Kundalini is not Advaitic Gnana.+

Kundalini is a yogic theory. Yogic people call it as Athma Shakti, which is inside the body.  Kundalini is not Advaitic Gnana. 

Yogis says Kundalini  power is dormant in 'muladhara' at the base of the spinal cord and that it must be roused and taken through the various 'chakras'  on to 'Sahasrara' at the top, in the brain, to attain Moksha.

Kundalini Shakti and Advaitic wisdom are not the same. The Self is not limited to the physical body but it pervades everything and everywhere in all three states.

The Kundalini is the yogic theory. Some yogis say the kundalini is in Ajna Chakra and some say the kundalini is in Mooladhara chakra.

All these yogic theories are based on the form of the Self, whereas the Soul, the Self is a formless, timeless, and spaceless existence.

Thus, whatever is based on the form(waking entity or ego) as the 'Self' has to be rejected because the form is the false self within the false experience(waking).

All the chakras are based on the waking entity (you or body), which is the false Self within the false experience (waking). When the Soul, the Self is formless the question of chakra does not arise.

Sage Sankara said:~ Neither by the practice of yoga nor philosophy, nor by good works nor by learning, does liberation come, but only through the realization that Atman and Brahman are one in no other way. (1) VivekaChudamani v 56, pg 25

By activating Kundalini- power one does not get non-dualistic or Advaitic wisdom. The wisdom does not dawn without realizing the universe is a dualistic illusion or Maya. The Soul, the Self is hidden by the dualistic illusion or Maya.

To realize the universe is an illusion is an impossible task through yogic practice, because yoga is limited to the physical entity, and it holds the universe as a reality.

As per some yogic texts: The Kundalini dwells in the Muladhara. when it is aroused, it passes along the Sushumna nerve, goes through the centers of Svadhisthana, Manipura, and so on, and at last reaches the head. This is called the movement of the Mahavayu, the Spiritual Current. It culminates in Samadhi.

Thus, Kundalini is subjected only to the physical body, and experienced as a body, whereas the Soul, the Self is not the body because the Soul, the Self is formless, timeless, and spaceless existence. Thus what value the kundalini will have when the Kundalini is based on form, time, and space?

Advaitic wisdom is based on the Soul, the Self, which is present in the form of consciousness. 

From the standpoint of the Soul, the Self, the universe, and all its contents are merely an illusion, created out of consciousness.

A Gnani is fully aware of the fact that everything in the universe is consciousness, whereas the yogi experiences only absent thoughts in the Samadhi, and when he comes out of Samadhi, he is unaware of the fact that the universe is an illusion because he considers his body as the author of the Samadhi. and his bodily experienced bliss as wisdom.:~Santthosh Kumaar
