Higher Self is a concept talked about in almost all esoteric traditions, and some exoteric traditions such as Krishna in the Bhagavad Gita. Communion with Higher Self is the initiation that is required to grasp divine will, which is the divine logos or masculine. Even the Gnostic Christian text, the Pistis Sophia, describes two (2) Christs: 1) Christ the Logos; and 2) Christ the Sophia, or the divine feminine. In all esoteric work, such communion is a stepping stone to fully engage in spiritual practices and it is what Aleister Crowley hinted towards with his motto, "Do What Thou Wilt". Do what thou "will" doesn't correlate to "doing whatever you want" as espoused by exoteric in their attempts to demonize Crowley, who was more than accepting of such backlash, but is an attempt to find one's divine will where Crowley concludes with "Love is the Law, Love under Will".
However, the appearance and location of such beings doesn't really attest to what "Higher Self" actually entails. We are to assume that such out-of-this-world type beings are extremely more advanced than humanity, or at least not tied to the wheel of samsara that perpetuates humanities suffering. Even going back in Hinduism under Puranic literature, we have the world filled with phenomenal beings with strange technology and weaponry that can only be described by our current human frame of thought as genetic manipulations, atomic-nuclear weaponry, and ufo-vimana based space crafts. However, these are all just external interpretations, that leave one wondering what Higher Self actually may be and its potential.
It took me probably two years of seeking, and using the law of attraction to manifest the highest information possible, to even get a glimpse of a logical understanding of what Higher Self may be. New Agers, Light-Workers, etc., all seem to discuss this expansive state of awareness, but can only describe it through how it makes them feel. Nonetheless, it is through Tantric Literature and wonderful commentaries posed by devotees, that I can begin to understand my Higher Self experiences from a logical perspective. After all, it is through these traditions that we have learned about Kundalini and the Chakras, stemming from secret Goddess traditions in India.
Shaivism (Christ the Logos; Divine Masculine):
Shaiva's and the likes are the shamanic traditions of India, where internal practices are stressed over ritualistic practices more closely aligned with the Vedic traditions. In addition, Bhakti (worship) is associated with Shiva, who is worshiped as Higher Self to be found and invoked within, as opposed to worshiped externally. But why Shiva, and not any other deity in the numerous pantheon found in Hinduism? Because Shiva is the ultimate yogi, the "yoke" between spirit and matter, who teaches the world to deify itself, or realize its own divinity. To take this one step further is what makes Shiva different, is his state of consciousness, Turiya aka Higher Self.
In these yogic teachings, there are three main states of consciousness: 1) Waking; 2) Dreaming; and 3) Deep Sleep. Deep sleep can be associated with the unconscious and subconscious, where also the collective consciousness plays a role. The realization that you are simply the "knower" or "experiencer" of all three (3) states of consciousness is the fourth state of consciousness, Turiya.
Within the unconscious subconscious, we tend to house quite a bit of ourselves, including issues we attempt to ignore only causing such issues to manifest in our external circumstances. To become aware of what lurks in this state of consciousness requires self-reflection, our own personal "judgment day". From hypnotherapy, we discover that we are controlled by hidden programming lurking deep within our psyche. With certain professionals, such as Dolores Cannon, we find that such issues can stem from prior life-times. Nonetheless, just as a candle flame dispels the darkness, our simple observatory awareness is enough to loosen the hold such issues pose on our psyche. Hence being awake/aware to what lurks within under deep sleep, our subconscious, is a key to unlocking who we are and why we have certain circumstances in our lives.
Dreaming is another state of consciousness, one that we can manipulate as taught by Tibetan Tantriks in teachings that create lucid dreams. From personal experience, lucidity begins within a dream where you realize you're dreaming. From there, one can proceed to move things around at will, though my experiences quickly diminish after such realization where I typically wake up thereafter. Nonetheless, here certain practitioners continue to do their spiritual work and exploration. Nonetheless, to be an observer within this state of mind seems to pose endless possibilities, where one quickly realizes that they control the dream matrix.
Lastly, the waking state is a bit odd and filled with numerous facets. We can choose to be the observer of our surrounding presence or our thoughts. Nonetheless, as opposed to looking at these state of consciousness as simply an observer, as observer of our surrounding and thoughts, we tend to get lost in our surrounding or thoughts letting the external circumstances control our awareness, as opposed to vice-versa (which is fine, we like to enjoy and get lost in our movies). Further, via law of attraction teachings, which I believe falls under "spanda" for Shaivas (though I still have quite a bit more to learn), our waking state can become like the lucid dream state, where we should be able to manifest the reality of our choosing, within the parameters of the collective belief systems. After all, the ancient mystics have consistently told us that what we deem to be reality is an illusion, or a holographic projection of consciousness, where law of attraction teaches to make this illusion lucid.
Therefore, to be Higher Self entails being awake/conscious/lucid of our awake state, dream state, and deep sleep state.
Shaktism (Christ the Sophia; Divine Feminine):
Kashmiri Shaivism seems to be solidified through the works of Abhinavagupta, who in his magnus opus, the Sri Tantraloka, indicates that if you can't find a human guru to help you with initiation, then turn to Adi-Shakti herself, Ma Kali, as she will initiate you. As someone who has astrological aspects that makes me despise guru worship, etc., as well as choosing to remove all societal-religious imposed limitations to seek to be unlimited, this was the best suited path for me. Given my love for this aspect of the divine, this path was probably the most easiest and most fun for me, my "permission slip" as Bashar would say.
Kali is associated with numerous Tantrik Goddesses (particularly Mahavidyas), where in Tantra, the wisdom and capabilities found in other deities should simply be instilled within the deity of your choice in order to evade being distracted. In other words, learn from other deities, but try to avoid constantly switching between them where the one chosen should hold the essence of all Tantrik deities. (Geshe Kelsang Gyatso, Guide To Dakini Land). As has been my experience, Kali works at the roots of the issues, while other more common deities in the Hindu pantheon will take a calm approach. Hence, Tantrik deities are the fast pass, a "no pain no gain" type of initial experience. In other words, they don't hesitate to put you in your place.
Tantrik Goddesses are almost always associated with the Kundalini energy slumbering at the bottom of one's spine, where Higher Self may reside in the higher chakras, particularly the 8th chakra above the Crown. An even fiercer form of Kali is when she is three (3) times as vicious as Tripura Bhairavi. Bhairavi as the feminine counterpart to Bhairava (Shiva in his "terrible" form) consists of Tripura meaning the three state of consciousness described above, and three (3) words: Bhavana (to manage); Ravana (to draw within); and Vamana (to expand). Hence, the generator (G), operator (O) and destroyer (D) paradigm that is exoterically associated with Brahma, Vishnu, Shiva, is esoterically found within Bhairavi(a). Hence, Bhairavi instills the G-O-D paradigm within the three (3) states of consciousness, which is the ability to create, manage, and destroy within the three (3) worlds.
Oddly, Tripura Sundari is not common for a Hindu household, though she permeates numerous other deities, including Krishna who is said to have invoked her essence, and Lakshmi similarly holds the title "Sri" and shares in the Sri Yantra. No doubt the Vaishnavas hold Krishna as their Tantrik deity, and Krishna is said to be the only essence to completely embody Brahman, or to fully accomplish the alchemical marriage within a human body. Moreover, Tripura Sundari is known to have a cult of her own as the Sri Vidya cult, with Vidya being sanskrit "vid" meaning to know (gnosis). Hence, just as the esoteric Christians had their Sophia, Tantriks have their Vidya. Often portrayed as a 16 year old as Sodashi, she represents the beauty of entering adulthood while still holding onto a childish heart, a Kumari, where as Jesus said, "...[t]ruly I say to you, unless you are converted and become like children, you will not enter the kingdom of heaven" (Matthew 18:3 NASB). Sodashi represents the pinnacle of spirituality, as she is symbolized as the peak of Mt. Meru, the abode of the Gods as expressed in her geometric form, the Sri Yantra.
In summation, the essence of Higher Self is to not only be awake/aware of the three (3) states of consciousness, but to be the most beautiful in all three (3). Law of attraction wise, to feel what it's like to be the most beautiful and consciously present in your waking state, in your dream state, and within your subconscious, seems to be the key to unlock our divine potential and manifest our very own heavenly abode, our own Mt. Meru.
