The principle of Yoga is to turn God-ward all or any of the powers of the human consciousness so that through that activity of the being there may be contact, relation, union. In the Yoga of Bhakti it is the emotional nature that is made the instrument. Its main principle is to adopt some human relation between man and the Divine Being by which through the ever intenser flowing of the heart's emotions towards him the human soul may at last be wedded to and grow one with him in a passion of divine Love. It is not ultimately the pure peace of oneness or the power and desireless will of oneness, but the ecstatic joy of union which the devotee seeks by his Yoga. Every feeling that can make the heart ready for this ecstasy the Yoga admits; everything that detracts from it must increasingly drop away as the strong union of love becomes closer and more perfect. <ref>http://incarnateword.in/cwsa/24/the-godward-emotions#p1</ref>
This is the weakness of the mind that it limits itself by its thoughts, its positive and negative ideas, the aspects of the Divine Reality that it sees, and tends too much to pit one against the other.
If the rift in the lid of mind is made, what happens is an opening of vision to something above us or a rising up towards it or a descent of its powers into our being. What we see by the opening of vision is an Infinity above us, an eternal Presence or an infinite Existence, an infinity of consciousness, an infinity of bliss,—a boundless Self, a boundless Light, a boundless Power, a boundless Ecstasy. It may be that for a long time all that is obtained is the occasional or frequent or constant vision of it and a longing and aspiration, but without anything further, because, although something in the mind, heart or other part of the being has opened to this experience, the lower nature as a whole is too heavy and obscure as yet for more. But there may be, instead of this first wide awareness from below or subsequently to it, an ascension of the mind to heights above: the nature of these heights we may not know or clearly discern, but some consequence of the ascent is felt; there is often too an awareness of infinite ascension and return but no record or translation of that higher state. This is because it has been superconscient to mind and therefore mind, when it rises into it, is unable at first to retain there its power of conscious discernment and defining experience…
