"Many people practice some form of kundalini yoga and deliberately arouse the kundalini energy at the base of the spine. This is extremely dangerous unless done under the supervision of an advanced initiate teacher. The fact that the fire of kundalini can be so roused does not constitute either initiation or enlightenment. It could lead to madness if the chakras are not prepared in advance to receive it. p. 97"
