Let the knower discriminate the knowledge and the Ignorance, the straight open levels and the crooked that shut in mortals. (Rig Veda 4.2.11)
Interpretation: He who would know the Truth should constantly discriminate between the real and the unreal, between oneness and division, between what leads to the Truth and what pushes away from it. When one so discriminates and follows only the way of Knowledge, the path is straight, wide, open and free. But if one were to choose the ways of ignorance, his path becomes crooked, devious, narrow and imprisoning.
To increase one’s consciousness is to grow in knowledge; to persist in unconsciousness and sink into it is to wallow in ignorance. One is the royal road to liberation; the other is the way to stay in captivity.
