Purification and consecration are two great necessities of sadhana. It is not a fact that one must be pure in heart before one can have any Yogic experience at all, but those who have experiences before purification is done run a great risk. It is much better to have the heart pure first, for then the way becomes safe. Nor can the Divine dwell in one’s consciousness, if that consciousness is obscure with impurity. It is for the same reason that I advocate the psychic change of the nature first—for that means the purification of the heart, the turning of it wholly to the Divine, the subjection of the mind, of the vital passions, desires, demands, of the physical instincts to the control of the inner being, the soul.
But all depends on your own standard and your own sincerity; and the more you are psychically ready the more you are led to the right source, the right master. The psychic and its faith are always sincere, but if in your exterior being there is insincerity and if you are seeking not spiritual life but personal powers, that can mislead you. It is that and not your faith that misleads you. Pure in itself, faith can get mixed up in the being with low movements and it is then that you are misled. <ref>http://incarnateword.in/cwm/03/faith#p2<ref>
If there is the will to surrender in the central being, then the psychic can come forward. <ref>http://incarnateword.in/cwsa/30/the-emergence-or-coming-forward-of-the-psychic#p29
