Integral Yoga understands the transformation of human nature as a comprehensive and progressive evolution of the whole being—mind, life, and body—rather than a mere inner escape or a single shift of consciousness. Human nature is viewed as a transitional, imperfect stage in a larger evolution of consciousness, moving from matter through life and mind toward supramental truth-consciousness. The aim is not to reject the world but to divinize it, so that every movement of thought, feeling, will, and action becomes a conscious expression of the Divine. This vision places spiritual practice within an evolutionary framework, where inner growth accelerates a larger cosmic process.

The process of change is often described as a threefold transformation: psychic, spiritual, and supramental. Psychic transformation centers on the awakening of the soul, or psychic being, as the true inner guide, gradually replacing the ego as the organizing principle of life. As this inner presence comes forward, motives are purified, and there is a shift from ego-centered desire to soul-centered aspiration, devotion, sincerity, and goodwill. Spiritual transformation then involves an opening to higher planes of consciousness above the ordinary mind, bringing experiences of peace, silence, wideness, and universal awareness. These higher powers descend into the mental, vital, and physical parts, reshaping them as instruments of a larger, more luminous consciousness.

Supramental transformation represents the most radical stage, in which the supramental or Truth-Consciousness becomes the governing power of the being. Here, not only inner states are refined; the very substance and laws of mind, life, and body are progressively reshaped by a higher truth-force. This is envisaged as the emergence of a gnostic or supramental being and a divinized life on earth, where human nature is no longer bound by ignorance and division. Such a transformation is integral, touching the physical, vital, mental, and subconscient levels, so that nothing in human nature remains outside the scope of the Divine influence.

In practice, this evolution is carried forward through a characteristic triad: aspiration, rejection, and surrender. Aspiration is the steady inner call for truth, light, peace, and union with the Divine; rejection is the conscious refusal of egoism, falsehood, desire, fear, and other lower movements; surrender is the offering of the whole being to the Divine Consciousness-Force, allowing it to work from within. Human effort prepares and opens the nature, but the decisive power of change is the descent and action of the Divine Shakti. Through this collaboration, the center of life gradually shifts from the separative ego to a deeper oneness with the Divine, and ordinary existence is progressively converted, purified, and divinized in all its activities and relationships.
