"The valley spirit never dies;
It is the woman, primal Mother.
Her gateway is the root of heaven and earth.
It is like a veil barely seen.
Use it will never fail. "

Lao Tsu – Tao Te Ching.

The state attained in Sahaja Yoga, also called the Sahaja Samadhi
is also very clearly described by the great mystic Ramana
Maharshi. A great realized soul, born in 1879 Ramana Maharshi
attained Enlightenment at the age of 17. He had many disciples but
like all other Gurus before the advent of Sahaja Yoga, he couldn't
give them en-masse Self-Realization. On the other hand he
described at length the nature of Self-Realization to his disciples.

"Question: What is Samadhi?
Ramana Maharshi: In Yoga the term is used to indicate some kind
of trance and there are various kinds of Samadhi. But the Samadhi
I speak to you about is different. It is the Sahaja Samadhi. In this
state you remain calm and composed during activity. You realize
that you are moved by the deeper Real Self within and are
unaffected by what you do or say or think. You have no worries,
anxieties, or cares, for you to realize that there is nothing that
belongs to you as ego and that everything is being done by
something with which you are in conscious union (Yoga)".
From the Teachings of Ramana Maharshi Edited by Arthur

The Kundalini has been described as the Key to Self-Enlightenment
and cosmic consciousness by various traditions. Here is a short
explanation by the famous psychoanalyst Carl Gustav Jung.

"The Kundalini is a microcosmic manifestation of the primordial
Energy or Shakti. It is the Universal Power as it is connected with
the finite body-mind. The object is to awaken Kundalini through
ritual practices and to enable Her ascent up the Susumna Nadi
through the Chakra System. When it reaches the topmost Chakra
the blissful union of Shiva and Shakti occurs. This lead to a far-
reaching transformation of the personality."
