Guruji, what is Kundalini and how to awaken the Kundalini?
Kunda means body, and Kundalini means the conscious energy in this body.
Whatever happens in meditations in the Advance Course is Kundalini itself. There is no other way to interpret Kundalini. If meditation happened, it would not be possible without the awakening of the Kundalini. If you went into meditation, it means the Kundalini has been awakened in you.
