"He is the Soul of the Universe; He is Immortal; His is the Rulership; He is the All-knowing, the All-pervading, the Protector of the Universe, the Eternal Ruler. None else is there efficient to govern the world eternally. He who at the beginning of creation projected Brahmâ (i.e. the universal consciousness), and who delivered the Vedas unto him — seeking liberation I go for refuge unto that effulgent One, whose light turns the understanding towards the Âtman."
Shvetâshvatara-Upanishad, VI. 17-18.
Definition of Bhakti
Bhakti-Yoga is a real, genuine search after the Lord, a search beginning, continuing, and ending in love. One single moment of the madness of extreme love to God brings us eternal freedom. "Bhakti", says Nârada in his explanation of the Bhakti-aphorisms, "is intense love to God"; "When a man gets it, he loves all, hates none; he becomes satisfied for ever"; "This love cannot be reduced to any earthly benefit", because so long as worldly desires last, that kind of love does not come; "Bhakti is greater than karma, greater than Yoga, because these are intended for an object in view, while Bhakti is its own fruition, its own means and its own end."
The one great advantage of Bhakti is that it is the easiest and the most natural way to reach the great divine end in view; its great disadvantage is that in its lower forms it oftentimes degenerates into hideous fanaticism.
It is not given to all of us to be harmonious in the building up of our characters in this life: yet we know that that character is of the noblest type in which all these three — knowledge and love and Yoga — are harmoniously fused. Three things are necessary for a bird to fly — the two wings and the tail as a rudder for steering. Jnana (Knowledge) is the one wing, Bhakti (Love) is the other, and Yoga is the tail that keeps up the balance. (III, 31 -33)
