I will refer you the thread containing this quote:
[QUOTE=Seeker33;27591]In this (Nath) cult we find a mystic and esoteric act of the transfer of spiritual energy from the master to the initiated aspirant and the act is known as Shaktipata. With the tremendous powers of the master, he can activate the Kundalini energy of the disciple. This transfer, he can do by touching a specific part of his body or simply by looking at him. This transfer of energy can be done on the aspirant who is at a great distance from the master. This is a peculiar mystical act. After the transfer of energy, the aspirant experiences a number of supernatural things, a tremendous flow (of liquid) light, etc. However, those scholars who are really anxious, should go through the book Awakening of Kundalini written by Pandit Gopi Krishna, who had undergone all these experiences before about twenty-five years in Kashmir. The concept of Shaktipata is not found in PYS(Patanjali’s Yoga Sutras).[/QUOTE]
It seems that this practice may have originated with the Nath Cult. Buddhists use a similar practice known as “empowerments”, in which the practitioner is not permitted to do certain practices unless he is authorized by a guru. This may be a variant of Shaktipat. It seems to me more along the lines of spiritual practice, and not necessarily yoga practice. I have not experienced this myself, so my ability to comment is limited.
