In plain words
On you, my tender babes, King Kaṃsa: how could his heart allow him to loose the maddened elephant? From the day I bore you, given over to hardships, what fruit of my karma is it that I must see it with my own eyes? Demons in human shape gathered to chase them through the city streets; how much Balarāma and Kṛṣṇa must have suffered!
Even Yaśodā, in those days, leaned on this fruit of karma alone. Yaśodā sat thinking only of the fruit of karma: that the torments the messengers sent by Kaṃsa had inflicted on Him from His very birth, and her seeing them, were the fruit of her own karma. But today people do not think about karma. We make some persons the excuse, “Because of them these troubles have come to me,” and we only go on blaming persons …. We do not think about the karmas we ourselves have to do. … not. So our own karmas are the cause of every result. No plant can come up without a seed. Without our karmas from past lives, this result cannot come to us. So you must do good karma and try to experience the good. Even one as great as Dharmarāja could not see that “the fruit of these karmas is the root cause of this sorrow of mine”. So for every person, happiness or sorrow, gain or loss, joy or grief, the root cause is the fruit of his own karma. More than all these karmas, to forget God's word, to defy it, is the root cause of still more karma. So it is essential that we take God's command upon our heads.
Even one as great as Rāma, parted from his beloved Sītā, wept like an ordinary man, brother. Who can tell what will come, on what day, in what way? What is to be lived through is certain, brother. The Pāṇḍavas of that age lived on leaves and roots and were cast out to the forest, brother.
What is the cause of this? For everything, karma is the cause. That is why the Vedas have taught the doctrine of karma as their chief aim and have given man every chance to enquire into it. So it is essential to recognise a sacred meaning in every saying and to act by it. We should never brood over persons. Try to look into your own duty.
