One who aspires to the ineffable Peace, one whose mind is awakened, whose thoughts are not entangled in the net of desire, that one is said to be "bound upstream" (towards perfection).
==For the Descent of Higher Consciousness==
A: By aspiration, the rejection of the lower movements, a call to a higher force. If you do not accept certain movements, then naturally, when they find that they can’t manifest, gradually they diminish in force and stop occurring. If you refuse to express everything that is of a lower kind, little by little the very thing disappears, and the consciousness is emptied of lower things. It is by refusing to give expression—I mean not only in action but also in thought, in feeling. When impulses, thoughts, emotions come, if you refuse to express them, if you push them aside and remain in a state of inner aspiration and calm, then gradually they lose their force and stop coming. So the consciousness is emptied of its lower movements.
The aspiration of the psychic being would then translate this demand entirely for the opening of the whole lower nature, mind, vital, body to the Divine, for the love and union with the Divine, for its presence and power within the heart, for the transformation of the mind, life and body by the descent of the higher consciousness into this instrumental being and nature.
Both aspirations are necessary for the fullness of this Yoga, the demand of the self on the nature from above, the psychic aspiration of the nature from below. When the psychic imposes its aspiration on the mind, vital and body, then they too aspire and this is what was felt by you as the aspiration from the level of the lower being. The aspiration felt above is that of the Jivatman for the higher consciousness with its realisation of the One to manifest in all the being. Both aspirations help and are necessary to each other. But the seeking of the lower being is at first intermittent and oppressed by the obscurity and limitations of the ordinary consciousness. It has by sadhana to become clear, constant, strong and enduring; it then compels realisation, makes it inevitable.<ref>http://incarnateword.in/cwsa/28/the-jivatman-in-the-integral-yoga#p50,p51</ref>
