In plain words
Truly, whatever we believe to be real, whatever we take to be permanent, all of them undergo changes in a moment. That is the very reason this world has the name martyaloka. That is, it is neither Satya nor Asatya. The world appears before our eyes and proclaims itself to be real. Suppose we believe that it looks real: in a little while it vanishes. So, since it is a form that appears and then does not, since it stands between the two, Satya and Asatya, it has another name too: sadasat (sat + asat). The scene we saw in the daytime does not appear in the night's dream. The feelings experienced in the night's dream cannot be recognised in the daytime as real. So our feelings are thrown into great confusion in just this state, where we cannot decide what is Satya and what is Asatya. The very bodies we saw in one month undergo changes in another month. The very feelings that arose in one moment change to their opposite in another moment. The very thoughts that sprang up in one moment turn round to their opposite in another moment. To live in this martyaloka holding such thoughts, such bodies, such feelings to be eternal and real is a very rare thing. Moreover, today, wherever we look in the world, we hear in many ways only things to do with sorrow, some news of deaths, some doings that have to do with unrest, acts of violence, some painful feelings; but feelings or news that let us hear of the immortality that makes our hearts swell with joy, we do not see at all, we do not hear.
This world is a fair of two days. Our life is a play of two hours. Our body? A bubble of water that lasts two minutes. Within such a scheme of things, we can understand for ourselves what fulfilment we should set about experiencing. The body is a house of diseases. Our household life is a bed of bugs; the world, a gathering of sorrows. Where will we find happiness here? So neither the body, nor the pleasure that belongs to the world, nor yet the desires that belong to sense objects give us any joy at all.
