The Master and Mover of our works is the One, the Universal and Supreme, the Eternal and Infinite. He is the transcendent unknown or unknowable Absolute, the unexpressed and unmanifested Ineffable above us; but he is also the Self of all beings, the Master of all worlds, transcending all worlds, the Light and the Guide, the All-Beautiful and All- Blissful, the Beloved and the Lover. He is the Cosmic Spirit and all-creating Energy around us; he is the Immanent within us. All that is is he, and he is the More than all that is, and we ourselves, though we know it not, are being of his being, force of his force, conscious with a consciousness derived from his; even our mortal existence is made out of his substance and there is an immortal within us that is a spark of the Light and Bliss that are for ever.
No matter whether by knowledge, works, love or any other means, to become aware of this truth of our being, to realise it, to make it effective here or elsewhere is the object of all Yoga.
