In plain words
Whether it is a pass or a fail lies in what one has written oneself. One does not know at once. After a month or a month and a half, the results come. The result comes according to what you wrote, not for what you did not write. That result is in your own writing. At the time it is not known. If you do a karma at one time, its result comes at another. Between this karma and the result of karma, a process of change goes on. Within that very process man's good and bad change. For every karma we have to experience its return. With this in view Emperor Manu told people to practise dharma.
When you make the organs of action and the organs of knowledge one, that is Śaraṇāgati
Students! There is a full-length mirror. Go and stand in front of that mirror and bow to the reflection. That reflection too will bow to you. Strike at the reflection. It strikes at you. Nature is like a mirror. Whatever karma you do in that mirror, all of it comes back to you, and to no one else. We cannot say that we did one thing and are experiencing another. Whatever we did, that is just what we experience. For some, the results may come at once. Some may come very late. Some may come in later births. Do not be proud, thinking, ‘I did wrong just now, and no result has come to me now.’ ‘Soon enough, ahead of you, lies the crocodiles' feast called old age’: so it comes on ahead. Some come at once. Look, I have just struck this table hard. You praise yourself for having struck the table hard. At that same moment the table struck you just as hard! In the same way, reaction, reflection, resound. There is no escaping this. In no circumstances can one escape it. So even before we do our karmas, we must practise good karmas. The Upaniṣads teach ‘Tasmai namaḥ karmaṇe’: that one should first of all bow to every karma. Why? That it may have good deeds done through us.
