It is no use trying to decide the things of the Spirit by the power and in the light of the intellect. The intellect can only reason and infer and its reasonings are partial and its inferences vitiated by error. One has to awaken the divinations in the soul, the psychic being, and wait for a higher knowledge which comes from above.
It is not safe to listen to or be influenced by the mental of other sadhaks. The Yoga aims at union with the Divine which will bring a spiritual oneness with other sadhaks, but a oneness in the Divine, in the Truth, not in the ignorance of the mind and the vital.
