In plain words
If it is only a matter of doing karmas, cattle, birds and beasts do karmas too. Karmas done through the limbs, the hands, the feet and the rest, are not karmas. You must enter into karma with the mind, with the Buddhi, with the Jñāna of discernment, with the Jñāna of Viveka. Whatever karma you enter into, you must inquire well whether it is a human karma or an animal karma. For humanness is wholly joined with the very nature of Brahman. It is infinite. It is beyond measure. To compare such divine and noble humanness with cattle, birds and beasts is a disgrace to humanness itself. ‘Karmānubandhīni manuṣyaloke.’ What karmas, and where did they come from, these karmas? What exists everywhere is the principle of Brahman alone! From this principle of Brahman arose ākāśa, which is sound. From this ākāśa came air. From this air, fire began. From fire, water arose. From water came earth. From earth, crops grew. From these crops, substance was formed. From this substance, humanness arose. Man is one who came by way of food. This food arose from the growing crop. The crop arose from the earth. Earth came from water. Water began from fire. Fire came from air. Air, in its turn, came from ākāśa. Ākāśa set out from Brahman. So food, Brahman and Ānanda are bound together in relation and kinship. Human life, which began with food, must end in Ānanda. That Ānanda is itself the principle of Brahman. ‘Brahmānandaṃ paramasukhadaṃ kevalaṃ jñānamūrtim...’ Where did Brahmānanda come from? What is this Brahmānanda like? Paramasukhadaṃ. Where did that happiness come from? Kevalaṃ jñānamūrtim. Ānanda arose from Jñāna, and through this Ānanda a ground was laid for humanness to live in this world.
Man Today Believes Material Pleasure Alone Is True Happiness
Man today does not himself understand what Ānanda is. He does not understand what happiness is. He takes the pleasure of things to be the chief happiness. He believes that this material pleasure alone is true happiness.
