Mistaking the spiritual heart within the body and it is located on the right side of the chest is a great error because the spiritual heart is the Soul.+

Raman Maharishi says "Here lies the Heart, the dynamic, spiritual Heart. It is called Hridaya and is located on the right side of the chest.

Santthosh Kumaar:~ Mistaking the spiritual heart within the body and it is located on the right side of the chest is a great error because the spiritual heart is the Soul, which is ever formless, timeless, and spaceless existence.

Sage Sankara says: ~ “What is accepted without a proper inquiry will not lead a person to the final goal. On the contrary, such acceptance will result only in evil, something which is detrimental to our spiritual progress.

Sage Sankara says :~VC-47 All the effects of ignorance, root, and branch, are burnt down by the fire of knowledge, which arises from discrimination between these two—the Self and the non-Self.

Until you think you are an individual separate from the world and the world existed prior to you and you are born in it afterward ignorance will prevail as a reality. Till ignorance is there the universe prevails as reality.

Sage Sankara says: ~ “The exercise in discrimination between real and unreal and renunciation of the false is real meditation, then why you are indulging in other types of meditation.

Perfect understanding and realization of ‘what is what’ leads to Self-awareness. By holding onto theories one remains in the realm of duality. You have to mentally go on dropping what is not the truth through deeper Self-search. Finally when you become aware of the fact that, your ego, your body, and the world are one in essence then there is Self-awareness in the midst of dualistic illusion or Maya.

Raman Maharshi said in (KNOW YOUR SELF~page 31):~ the location of the Heart is of the chest and not on the left. The light of the consciousness flows from the heart to through Sushumna's channel to ‘Sahasrarara’.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 death.

The ‘Sahasrara’ 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 Nirvikalpa 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.

Some other Gurus also propagate the Nadi you refer to is called Amrita Nadi. It connects the Spiritual Heart with the Sahasrara. It is best to merge in the Heart and then see that the Heart is beyond time and space.

But

Santthosh Kumaar:~ Deeper self-search reveals:~ When the ‘Self’ is not the body then the location of the Heart is of the chest and not on the left. The light of the consciousness flows from the heart to through Sushumna's channel to ‘Sahasrara’ have no value. All these concepts are yogic and they have no value in the Atmic path.

When the ‘Self’ is not the body, the question of the Amrita Nadi or Sahasrara does not arise. Until we think the ‘Self’ is within the body it is impossible to cross the threshold of dualistic illusion.

Deeper self-search reveals the fact that the ‘Self’ is not the body then why bring Nadi, and chakras when they are part and parcel of the body.

Deeper self-search reveals the fact that the ‘Self’ is neither the body nor the ‘I’. Thus, one has to go beyond the ‘I’ means beyond the form, time, and space to realize 'Self' is a formless, timeless, and spaceless existence.

The Soul, the Self is unborn and eternal because it is ever formless, timeless, and spaceless existence.

Remember:~

Raman 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: ~ ‘The spiritual heart is the Soul, the Self, not the physical heart. The world in which you exist is merely an illusion created out of the Soul, the spiritual heart, which is present in the form of consciousness.

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 statement 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.

The Seeker must realize the Soul, the Self, itself is the spiritual heart. The Soul, the spiritual heart is ever formless, timeless, and spaceless existence.

The Soul itself is the spiritual heart that is present in the form of the Spirit or consciousness. :~ Santthosh Kumaar
