The whole life is a succession of dreams. My ambition is to be a conscious dreamer, that is all.

Each soul is potentially divine. The goal is to manifest this divinity within, 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.

The whole universe is one. There is only one Self in the universe, only One Existence.

You cannot believe in God until you believe in yourself.

In a day when you don't come across any problems—you can be sure that you are traveling in the wrong path.

Arise, Awake and Stop not till the Goal is Reached.

To succeed, you must have tremendous perseverance, tremendous will. “I will drink the ocean”, says the persevering soul; “at my will mountains will crumble up”. Have that sort of energy, that sort of will; work hard, and you will reach the goal.
