With pure feelings we can have the vision of truth.

... In this nether realms of Life all kinds of contraries are mixed up. Truth and error, Wisdom and Ignorance, Death and Life are all mingled in this valley of fleeting Gleams. Souls trapped in this region become agents of Life’s desires, not their masters. Some, however, warily pass across and reach a greater life 

What is nether loka or world? There are 14 worlds in the body of all. There are 7 higher worlds above the stomach and 7 which are called the nether worlds below. I have written of this before in many books. They are all opposites, contradictions. For the one whose Atma is here, he cannot go upward. Though this man lives in a human body, he lives like an animal. Here, sadhakas need more awareness. One must struggle with these contradictions and go beyond them. Even the great sages and rishis have been cheated here. I have written two books on Miracle Maya.
