In plain words
But we must keep the divine path in the citta to some extent and try to nourish that, too. So it is not a matter of calling ourselves yogis, or rogis, or bhogis. For every single human being, in the principle of these four, the yogi, the bhogi, the jogi and the bairāgi, divine sacrifice alone is the same in all. So this sacrifice itself is the chief quality for every human being.
Students! The Upaniṣads went on offering such great matters so very simply. Man is not trying to recognise that subtle matter. In every single thing there is a secret. Where is this secret? The secret is in sorrows. On this very basis they went on showing: Praśānti within aśānti, radiance within Praśānti, the supreme light within radiance, and the principle of the Paramātma within the supreme light. So if there is no darkness at all, the light has no value. If there is no hunger at all, we give no value even to food; if there is no heat at all, no one buys an air conditioner. On this very basis: Na sukhāt labhyate sukhaṃ. We do not gain happiness through happiness. We gain happiness through hardship and sorrow. If we sit in an air-conditioned room for all twenty-four hours, no one knows the value of air conditioning. When we wander about in the sun for two hours and come back into the air-conditioned room, we understand its value. Human life is made up of happiness and sorrow. It is made up of gain and loss. It is made up of cold and heat. If these two feelings were not there, if there were no duality, non-duality would have no value. Man is somewhat blind. A man with dual mind is half blind. So we have set ourselves on two kinds of path, saying "that" and "this". That is tat. This is tvam. This is I. That is he. He and I. We must journey to the oneness within the two. From I we must reach He. It is not from untruth to truth that we must journey. Lesser truth to higher truth. What is it like? There is a big circle.
That is whole, this is whole; out of the whole the whole comes forth; taking the whole out of the whole, the whole alone remains.
