Some people feel that if a yogi reaches a stage of knowledge about the past
and future, he would be omniscient, but that is an exaggeration. Such
information will not affect the course of history nor change the probability, nor
affect how the Supreme Being relates to the limited personalities. Its value is in
the potency to convince the yogi to make an exit from these gross and subtle
mundane histories. But that is not all, because a yogin has to acquire
permission to do that. That permission must be gained from the Supreme
Being, who might not grant it to a particular yogin.
