And this is Maya

 Like moths hurling themselves against the flame, we are hurling ourselves again and again into sense-pleasures, hoping to find satisfaction there. We return again and again with freshened energy;thus we go on, till crippled and cheated we die. And this is Maya.

In the desire to solve the mysteries of the universe, we cannot stop our questioning, we feel we must know and cannot believe that no knowledge is to be gained. A few steps, and there arises the wall of beginningless and endless time which we cannot surmount. A few steps, and there appears a wall of boundless space which cannot be surmounted, and the whole is irrevocably bound in by the walls of cause and effect. We cannot go beyond them. Yet, we struggle, and still have to struggle. And this is Maya. 

With every breath, with every pulsation of the heart, with every one of our movements, we think we are free, and the very same moment we are shown that we are not. Bound slaves, nature's bond-slaves, in body, in mind, in all our thoughts, in all our feelings. And this is maya.
