In plain words
By karma the creature is born, by karma it grows, by karma it passes away; karma is God to man; karma is the cause of joy and sorrow in this world!
Karma is the very life-breath of man. Every human being, from the time he rises at dawn until he lies down at night, must recognise what kind of deeds he is doing, and do them accordingly. This is man’s chief duty. Bats move through the sky like all birds, and alight on trees to rest. But unlike the other birds, they hang from the branches with their heads down and their feet up. Has anyone wound a thread round them and tied them upside down to the branches? No. It happens that way according to their own karma. In the examination, if you write the right answers to all the questions the teachers ask, you get good marks. If you write some mistakes in them, your marks go down too. In the same way, as are the deeds we do, so is the fruit that comes to us. When we have bad intentions and do bad deeds, we experience only bad as their fruit; when we do good deeds, we receive only good fruit, in keeping with them. But man today does bad and hopes to receive good. No one does good and wishes to receive bad. Yet each thing must bring the fruit that fits it.
Every person must weigh the good and bad in the deeds he does. To do bad deeds is the mark of an animal. To do good deeds is man’s chief duty.
