Each soul is potentially divine. The goal is to manifest this divinity by controlling nature, external and internal. Do this either by work, or worship, or psychic control, or philosophy - by one, or more, or all of these - and be free. This is the whole of religion. Doctrines, or dogmas, or rituals, or books, or temples, or forms, are but secondary details.
Swami VivekanandaGive up the idea that by ruling over others you can do any good to them. But you can do just as much as you can in the case of the plant: you can supply the growing seed with the materials for the making up of its body, bringing to it the earth, the water, the air, that it wants. It will take all that it wants by its own nature, it will assimilate and grow by its own nature.
Swami VivekanandaOnly love for the Supreme Lord is true Bhakti. Love for any other being, however great, is not Bhakti. The "Supreme Lord" here means Ishvara, the concept of which transcends what you in the West mean by the personal God. "He from whom this universe proceeds, in whom it rests, and to whom it returns, He is Ishvara, the Eternal, the Pure, the All-Merciful, the Almighty, the Ever-Free, the All-Knowing, the Teacher of all teachers, the Lord who of His own nature is inexpressible Love."
Swami VivekanandaEven the greatest fool can accomplish a task if it be after his heart. But the intelligent man is he who can convert every work into one that suits his taste. No work is petty. Everything in this world is like a banyan seed, which, though appearing tiny as a mustard seed, has yet the gigantic banyan tree latent with it. He indeed is intelligent who notices this and succeeds in making all work truly great.
