Kundalini

Kundalini is the Mother of the world, who illumines the self

and gives shade to the sprouted seed of the universe.
It is the embodiment of the formless Brahman,
the cask of Lord Shiva,
the main spring of the sacred syllable Om.

- Shri Jnaneshwara (Dnyaneshwara. also known as Jñanadeva) (1275-1296), Jnaneshwari (Dnyaneshwari)
