Some yoga practitioners may wonder whether Kundalini is essential to awakening. In this video, Mooji explains the answer very nicely.
In addition, David Godman noted:
“Sri Ramana Maharshi never advised his devotees to practice Kundalini Yoga since he regarded it as being both potentially dangerous and unnecessary. He accepted the existence of the Kundalini power and the Chakras but he said that even if the Kundalini reached the Sahasrara it would not result in realisation. For final realisation, he said, the Kundalini must go beyond the Sahasrara, down another Nadi (psychic nerve) he called Amritanadi (also called the Paranadi or Jivanadi) and into the Heart-centre on the right hand side of the chest. Since he maintained that self-enquiry would automatically send the Kundalini to the Heart-centre, he taught that separate yoga exercises were unnecessary.
The practitioners of Kundalini Yoga concentrate on psychic centres (Chakras) in the body in order to generate a spiritual power they call Kundalini. The aim of this practice is to force the Kundalini up the psychic channel (the Sushumna) which runs from the base of the spine to the brain. The Kundalini Yogi believes that when this power reaches the Sahasrara (the highest Chakra located in the brain), Self-realisation will result.
Sri Ramana Maharshi taught that the Self is reached by the search for the origin of the ego and by diving into the Heart. This is the direct method of Self-realisation. One who adopts it need not worry about Nadis, the brain centre (Sahasrara), the Sushumna, the Paranadi, the Kundalini, Pranayama or the six centres (Chakras).”
