Psychic realization means finding the soul with its attendant consequences of ahaituki (unconditional) bhakti and absolute self giving to the Divine. Psychicisation means all the parts of our mental, vital, physical nature, all the movements surrender to the Divine and do not seek anymore their own satisfaction but seek to become an instrument of the Divine and serve the Divine for His joy and His work, to fulfil His Will in everything.
Spiritual Realization means realising the One Self above the mind and behind everything. It beings freedom from the ego and an abiding Peace and the knowledge that liberates us from all bondage. Spiritualization means the descent of light, knowledge, power, peace, joy, wideness of the Higher Consciousness and the emergence of new faculties of knowing and action such as inspiration, revelation, intuition and a corresponding change in the mind and heart and life and even the body.
Were Psychicization and Spiritualization already done in Old Yogas?
Realisation yes but its full impact upon nature rarely so except in few Vedic Rishis.
