Yoga exercises are excellent; the speaker does them every day, for an hour or more; but that is merely physical exercise, to keep the body healthy, and so on.
Our brains are so conditioned through education, through religion, to think we are separate entities with separate souls and so on. We are not individuals at all. We are the result of thousands of years of human experience, human endeavor and struggle.
Hitler and Mussolini were only the primary spokesmen for the attitude of domination and craving for power that are in the heart of almost everyone. Until the source is cleared, there will always be confusion and hate, wars and class antagonisms.
To be free of all authority, of your own and that of another, is to die to everything of yesterday, so that your mind is always fresh, always young, innocent, full of vigour and passion. It is only in that state that one learns and observes. And for this, a great deal of awareness is required, actual awareness of what is going on inside yourself, without correcting it or telling it what it should or should not be, because the moment you correct it you have established another authority, a censor.
Instead of old spiritual distinctions you have new spiritual distinctions, instead of old worships you have new worships. You are all depending for your spirituality on someone else, for your happiness on someone else, for your enlightenment on someone else.
Religion becomes a matter of belief, and belief acts as a limitation on the mind; and the mind then is never free. But it is only in freedom that you can find out what is true, what is God, not through any belief; because your belief projects what you think God ought to be, what you think ought to be true. If you believe God is love, God is good, God is this or that, your very belief prevents you from understanding what is God, what is true.
The more you know yourself, the more clarity there is. Self-knowledge has no end - you don't come to an achievement, you don't come to a conclusion. It is an endless river.
