Ishvara is the highest manifestation of the Absolute Reality, or in other words, the highest possible reading of the Absolute by the human mind. Creation is eternal, and so also is Ishvara.
Swami VivekanandaAlways remember that renunciation is the root idea. Unless one is initiated into this idea, not even Brahma and the World - gods have the power to attain Mukti
Swami VivekanandaJesus Christ was God - the Personal God become man. He has manifested Himself many times in different forms and these alone are what you can worship. God in His absolute nature is not to be worshipped. Worshipping such God would be nonsense. We have to worship Jesus Christ, the human manifestation, as God. You cannot worship anything higher than the manifestation of God. The sooner you give up the worship of God separate from Christ, the better for you.
Swami Vivekananda
