One may practice yoga and get illuminations in the mind and the reason; one may conquer power and luxuriate in all kinds of experiences in the vital; one may establish even surprising physical Siddhis; but if the true soul-power behind does not manifest, if the psychic nature does not come into the front, nothing genuine has been done. In this yoga the psychic is that which opens the rest of the nature to the true supramental light and finally to the supreme Ananda.
If the inmost soul is awakened, if there is a new birth out of the mere mental, vital and physical into the psychic consciousness, then this yoga can be done; otherwise (by the sole power of the mind or any other part) it is impossible... If there is refusal of the psychic new birth, a refusal to become the child new born from the Mother, owing to attachment to intellectual knowledge or mental ideas or to some vital desire, then there will be failure in the sadhana.
In Yoga also it is the Divine who is the Sadhaka and the Sadhana; it is her Shakti with her light, power, knowledge, consciousness, Ananda, acting upon the Adhara, pouring into it these divine forces that make the Sadhana possible. But so long as the lower nature is active, the personal effort of the Sadhaka remains necessary.
At last he wakes into spiritual mind;
A high liberty begins and luminous room:
He glimpses eternity, touches the infinite,
He meets the gods in great sudden hours,
He feels the universe as his larger self,
Makes Space and Time his opportunity
To join the heights and depths of being in light,
In the heart's cave speaks secretly with God.
