The Triple Transformation in Sri Aurobindo's integral yoga refers to the two-fold movement of spiritual transformation - the inward pychicisation by which the sadhak gets in contact with the inner divine principle or Psychic Being, and the spiritual transformation or spiritualisation.
The former represents the Inner Guide which is realised through the Heart, the latter can be compared to the traditional concept of Vedantic, Buddhist and popular guru Enlightenment and the descriptions of the Causal and Ultimate stages of spiritual development in the evolutionary philosophy of the integral thinker Ken Wilber.
For Sri Aurobindo, both these stages are equally necessary and important, as both serve as necessary prerequisites for the third and by far the most difficult element of change in the triple transformation, the Supramentalisation of the entire being.
...One must first acquire an inner Yogic consciousness and replace by it our ordinary view of things, natural movements, motives of life; one must revolutionise the whole present build of our being. Next, we have to go still deeper, discover our veiled psychic entity and in its light and under its government psychicise our inner and outer parts, turn mind-nature, life-nature, body-nature and all our mental, vital, physical action and states and movements into a conscious instrumentation of the soul. Afterwards or concurrently we have to spiritualise the being in its entirety by a descent of a divine Light, Force, Purity, Knowledge, freedom and wideness. It is necessary to break down the limits of the personal mind, life and physicality, dissolve the ego, enter into the cosmic consciousness, realise the self, acquire a spiritualised and universalised mind and heart, life-force, physical consciousness. Then only the passage into the supramental consciousness begins to become possible, and even then there is a difficult ascent to make each stage of which is a separate arduous achievement.— Sri Aurobindo, The Synthesis of Yoga, 281-2
