Chemistry ceases to improve when one element is found from which all others are deductible. Physics ceases to progress when one force is found of which all others are manifestations. So religion ceases to progress when unity is reached, which is the case with Hinduism.
There is this difference between the love taught by Christianity and that taught by Hinduism: Christianity teaches us to love our neighbours as we should wish them to love us; Hinduism asks us to love them as ourselves, in fact to see ourselves in them.
Each one of you has a glorious future if you dare believe me. Have a tremendous faith in yourselves, like the faith I had when I was I was young... Have that faith, each one of you, in yourself - that eternal power is lodged in every soul - and you will revive the whole of India.
With everything we do in life we identify ourselves. Here is a man who says harsh words to me. I feel anger coming on me. In a few seconds anger and I are one, and then comes misery. Attach yourselves to the Lord and to nothing else, because everything else is unreal. Attachment to the unreal will bring misery. There is only one Existence that is real, only one Life in which there is neither object nor [subject].
