Question: At what stage of the development of the soul is the kundalini released from the base of the spine and starts moving toward the aperture of Brahman?

Sri Chinmoy: There is no hard and fast rule. There are many people who realise God without developing the kundalini power. Again, there are those who have not realised God, but who will realise God in, say, two or three incarnations, who have already developed kundalini power. It is not that the soul's development or the soul's evolution need have any direct connection with the kundalini. The soul's evolution means the soul's manifestation. There are many who have seen the gradual revelation and manifestation of their soul's potentialities and possibilities who have not developed their kundalini power. Instead, they get spiritual power from God.
