The words Rtambhara mean filled with higher truth, essence, supreme cognition; Tatra means there and Prajna means knowledge, wisdom, and insight. When consciousness dwells in wisdom, a truth-bearing state of direct spiritual perception dawns. This acquired spiritual enlightenment is filled with unalloyed wisdom, lustrous in truth and reality. This luminosity of the soul manifests, gleaming with full fragrance. Rtambhara prajna is a state of seasoned intelligence or ripened wisdom, companioned with passionate insight.
This sutra talks about the stage of highest knowledge. It is technical and truth bearing. This is not an ordinary state of knowledge. In this state, whatever the person says turns out correct and sees turns out accurate. This is possible because the yogi's mind becomes free from thoughts and he enjoys the bliss of a perfect and totally pure state of mind. Rtambhara tatra prajna is the kind of capacity when the Yogi becomes internally so clear, so accurate, that he never goes wrong. The mind becomes crystal clear and with that mind, only truth flows. According to Swami Satchidananda, when one achieves ritambhara prajna, one can understand everything without study. And when one can transcend the mind with proper concentration, one can feel the cosmic force or God. It means in ritambhara prajna one transcends the mind and gains a knowledge that is realization. And in order for that to happen, the mind must be completely silent which can be achieved through years of practicing.
The yogi or the practitioner reaches the state of conscious mind which is purified. His intellect gets cleansed, guilt-free and also stable. When the yogi reaches such a purified state of conscious mind, he attains illumination of true self-consciousness. He experiences self-conscious that is truth bearing. Such enlightenment is saturated with harmony and righteousness. The practitioner gets liberated from the foul smell of wrong thought. He reaches such a stage where the thoughts of worldly goods, worldly possessions and worldly pursuits become tasteless.
