When the Self is not the body, but the Self is the formless Soul, then the question of ‘Sahasrara’ and 'Sushumna’ does not arise, because ‘Sahasrara’ and ‘Sushumna' are within the body.+

Dattatreya's Song of the Avadhut 1.36-42:~ Non-duality is taught by some; some others teach duality. They don't understand that the all-pervading Reality is beyond both duality and non-duality.

Sage  Ramana Maharshi: ~ "The location of the Heart is of the chest and not on the left. The light of the consciousness flows from the heart through the Sushumna channel to ‘Sahasrarara’.(KNOW YOUR SELF~page 31)~

From ‘Sahasrarara’ consciousness spreads all over the body, then the experience of the world arises. Viewing themselves as different from that consciousness human beings get caught up in the cycle of birth and deaths.  

 The ‘Sahasrarara’ of one who abides in the Self is pure light only. Any thoughts which approach it cannot survive.

Even when objects are perceived, because of their nearness, it does not destroy yoga as the mind sees no differences.

The state in which awareness is firm,  even when objects are sensed, is called the natural state.  In Nivikalpa Samadhi, there is no objective perception.

The entire universe is in the body and the whole body is in the Heart. Hence, the universe is contained within the Heart. 

Sage Ramana Maharishi: ~ He placed his right hand on his right breast and continued, "Here lies the Heart, the dynamic, spiritual Heart. It is called Hridaya and is located on the right side of the chest and is clearly visible to the inner eye of an adept on the spiritual path. Through meditation, you can learn to find the Self in the cave of this Heart." ~ Mercedes de Acosta, Here Lies the Heart

Santthosh Kumaar: ~ When the Self is not the body,  but the Self is the formless Soul,  then the question of  ‘Sahasrara’ and  'Sushumna’ does not arise,  because ‘Sahasrara’ and  ‘Sushumna' are within the body. 

The spiritual heart is the Soul, the Self, not the physical heart. The world in which you exist is within the Soul, the spiritual heart. 

Mistaking the spiritual heart within the body is a great error. Even some Advaitic guru says that the Self is within the spiritual heart. And the spiritual heart is on the left side.  Such a declaration is merely an imagination, based on the false self. 

When the Self is bodiless, then the question of the heart being left side or right side does not arise.  

Brihadaranyaka Upanishad:~  The Self is indeed Brahman, but through ignorance, people identify it with intellect, mind, senses, passions, and the elements of earth, water, air, space, and fire. This is why the Self is said to consist of this and that and appears to be everything. 

The Self is not ‘I’ but the Self is the formless Soul. The Soul is present in the form of consciousness. Consciousness is the substance and witness of the ‘I’. 

When one realizes the Soul is the Self then he is freed from experiencing the dualistic illusion or Maya as reality.

The falsehood is present in the form of ‘I’ (mind or universe).the ‘I’ is the cause of ignorance.  

If one crosses the ‘I’ (mind or universe) than the Self in the kingdom of nondual heaven without the body and without the experience of the world (waking).

The seeker must realize the Soul, the Self, itself is the spiritual heart.  The Soul the spiritual heart is ever formless. The Soul itself is the spiritual heart is present in the form of the Spirit or consciousness.

Without the form, time, and space, the Soul, the Self, becomes naked. The nature of the Soul, the Self is formless, timeless, and spaceless existence. 

Consciousness is self-evident. It is not established by extraneous proofs. It is not possible to deny consciousness because it is the very essence of the one who denies it. Consciousness is the basis of all kinds of knowledge, presuppositions, and proofs. Consciousness is the true Self.  

Consciousness is within, the consciousness is without; the consciousness is before, the consciousness is behind;  consciousness is on the right, consciousness is on the left;  consciousness is above and consciousness is below.  

Until one thinks his body as body, ego as ego the universe as the universe he remains in ignorance because he is still in ignorance and he is unaware of the fact that they too are consciousness.  

A Gnani sees only unity in diversity, just like a goldsmith estimating the gold in various items of jewelry sees only gold. 

When one identifies the Self with the form then only the form, time, and space are present. But when one transcends form, time and space the duality never remain as reality.:~Santthosh Kumaar
