In plain words
Then a longing to know arose in him: “Whatever we think is permanent is all impermanent.” All this while I relied on these things and wasted my life. The body is bound up with the six changes, such as being born, growing, wasting away, growing old and dying. To trust a body subject to the six changes is nothing but ignorance, he thought. With a desire to gain spiritual knowledge he went to a guru. 'My son! What sādhanas have you been doing until now?' the guru asked. 'I have done no sādhana at all. Because troubles came, my mind was turned. The moment I sit for meditation, my cow stands before me. I raised her with such love. Because of my attachment to her, she comes and stands before my eyes,' he said. Then the guru: 'My son! What has gone by has gone by. There is no need to grieve. In every thing there are asti, bhāti, priya, rūpa and nāma. These same are also called Sat, Cit, Ānanda, rūpa and nāma. They are in the cow you see too. Set apart the rūpa and nāma, and practise asti, bhāti and priya. Give up the rūpa and nāma and meditate, “I am Sat-Cit-Ānanda”,' he taught. Doing sādhana in this way at the guru's command, he became one with the awareness of Saccidānanda.
Brooding and grieving over what has gone by is a great obstacle. What has happened has happened. It will not come back. What use is there in brooding over it again? We have come all this way looking at the road we walked. From now on we must look only at the road ahead. Brooding over the past throws your mind into turmoil. So you must not go on recalling past troubles or sorrows and brooding over them. Brooding in that way makes the past an obstacle.
The obstacle of the present
Now, the present. Man feels that everyone must respect him, show him humility and obedience, act according to his command, and that every single one must trust him.
