That's a good question. I was wondering the same. I thought Kundalini was a serpentine force within the human that arose from the Root Chakra and to the Crown Chakra while doing certain Tantric Yoga Asanas. It's a Hindu teaching. So I suppose they are saying that these flaky churchan tares are practicing some sort of yoga posture of Hinduism or something.
You don't need to do yoga postures to release kundalini, in this video they show "shaktipat", which they call "anointing" to make it appear to be Christian. It's not Christian.
Shaktipat - Wikipedia, the free encyclopedia
"Shaktipat or Śaktipāta (Sanskrit, from shakti - "(psychic) energy" - and pāta, "to fall")[1] refers in Hinduism to the conferring of spiritual "energy" upon one person by another. Shaktipat can be transmitted with a sacred word or mantra, or by a look, thought or touch - the last usually to the ajna chakra or third eye of the recipient."
