Omniscience or the wisdom of knowing, is a facet of the making of omnipresence (everpresent or oneness with everything).
Although not something that is developed early (waiting untill chakra 39 and 40 to develop), it is the essence of Omniscience one of the four characteristics of Godliness that demonstrates how man progresses towards greater divinity.
One great account of a mahayogis use of omniscience is the famed story from Autobiography of a Yogi (P. Yogananda) were he tell the story of Lahiri Mahasaya the great Kriya yogi who said the following:
“I am drowning in the bodies of many souls off the coast of Japan!”
This as he was discussing or performing a sermon on Christ consciousness, the state of vibratory guru or Christ that helps remove karma from disciples. It was not untill the next day that the disciples of Lahiri who were at the discourse read that a boat sank the day before off the coast of Japan.
It is this bifactorial nature of both Christ consciousness (removing pain and suffering from the men and women who died off the coast of Japan) plus Omniscience (ever or all knowing) that depends the providence that Kriya, Yoga, and Divinity from God are examples that man can strive for and achieve.
For more surprising details on spiritual progression, explanation of development and how one moves to greater divinity and godliness look for the soon to be released book by Dr. Greszczyszyn called The Complete Chakra System.
