“The obstacle is also called Kuṇḍalinī because it looks like an earring
worn by women in the olden days and Kuṇḍali means ‘earring’.
It is also called Śakti because its power is so great that
it is able to block the flow of Prāṇa into the Suṣumṇā.
We must note that it is Prāṇa that is eventually
supposed to go into the Suṣumṇā.
Many books describe that which goes up as Kuṇḍalinī.
Kuṇḍalinī does not go up.
Suṣumṇā is like a conductor through which energy flows.
This energy is the same energy that is always present, Prāṇa.”
