The seeker may experience the Brahman, the Divine Consciousness within himself, just as he may experience the Brahman in the universal manifestation or in the transcendent that exceeds and is independent of the entire manifestation, individual and universal.
Within the individual seeker, there are several ways the Brahman may reveal himself, as Sri Aurobindo here describes: “Within us there are two centres of the Purusha, the inner Soul through which he touches us to our awakening; there is the Purusha in the lotus of the heart which opens upward all our powers and the Purusha in the thousand-petalled lotus whence descend through the thought and will, opening the third eye in us, the lightnings of vision and the fire of the divine energy. The bliss existence may come to us through either one of these centres.”
The experience of the heart-lotus opening brings about the following: “When the lotus of the heart breaks open, we feel a divine joy, love and peace expanding in us like a flower of light which irradiates the whole being. They can then unite themselves with their secret source, the Divine in our hearts, and adore him as in a temple; they can flow upwards to take possession of the thought and the will and break out upward towards the Transcendent; they stream out in thought and feeling and act towards all that is around us.”
This experience comes and goes as long as there are parts of the being that put up any resistance, and it is thus necessary to undertake patient and persistent effort of purification and concentration to make the experience constant and all-pervasive in the being.
“When the upper lotus opens, the whole mind becomes full of a divine light, joy and power, behind which is the Divine, the Lord of our being on his throne with our soul beside him or drawn inward into his rays; all the thought and will become then a luminosity, power and ecstasy; in communication with the Transcendent, this can pour down towards our mortal members and flow by them outwards on the world.”
This experience, too, is subject to variations due to the inability of the instrument to hold and fix the intensity for long periods of time without break. “…but as we grow in the power to hold this new existence, we become able to look long on the sun from which this irradiation proceeds and in our inner being we can grow one body with it.”
The poise of the seeker can also aid in the process. “Sometimes the rapidity of this change depends on the strength of our longing for the Divine thus revealed, and on the intensity of our force of seeking; but at others it proceeds rather by a passive surrender to the rhythms of his all-wise working which acts always by its own at first inscrutable method. But the latter becomes the foundation when our love and trust are complete and our whole being lies in the clasp of a Power that is perfect love and wisdom.”
