In plain words
So all the peace of the world rests on the individual. The world and the individual, both of them, rest on Manas. So we must make the proper effort to keep Manas on the right path. A fish travels against the current of the water and tries to escape its danger by itself. In the same way, man must move against bad saṅkalpas, check them, and try to escape his danger. The men of today cannot recognise even the cleverness that a fish has. Today's man is creating his own danger himself.
Today's man is himself becoming the cause of his own pleasure and pain. Others are not the cause of our troubles and losses, of our pleasures and pains, or of our sorrows. Our saṅkalpas alone are the cause of these. For this tree of saṃsāra, with its many branches of thoughts, Manas is the root. Only when we root out Manas is the tree rooted out too. What is this saṃsāra? Is it the family, with wife and children? No. No. Saṃsāra means nothing but saṅkalpa. The very foundation of this saṅkalpa is Manas itself. When we root out this Manas that is the root, the tree that is saṃsāra is rooted out. But you may doubt whether there is another way to root out Manas. Everything has a beginning and an end. A person who is born, and a thing, have an end. Not a single thing in this world is permanent. That is why they called it 'anityam asukhaṃ lokam'. If from this, which is impermanent and passing, we are to attain the principle that is eternal Satya, then this very principle of the Ātma is the true path; this very principle of the Ātma is the right path. That is why: 'Caste of humanity'. Humanness itself stays as oneness in all. What is the same in everyone is Manas itself.
But this sameness is undergoing change just because it stays apart. The form of Manas changes into colours. Has Manas got colours? If you ask: it has. Manas full of anger is red. Manas full of selfishness is the colour of wheat. Manas filled with Ahaṅkāra is the colour of an orange.
