In plain words
When he sees an employee at a lower level than himself, he is content: ‘Oh, he is at a lower level than I am.’ So, to begin with, if we want to root out envy, we must follow a path like this. Little by little this outlook makes it possible, even when we see an employee higher than ourselves, even when we see people in a higher position, even when we see someone who got higher marks, gradually to turn all this into evenness. Above all, whether you see someone greater or someone at a lower level than yourself, you must cultivate the divine quality of developing an even mind. There is nothing wrong in hoping to reach that level yourself; but to notice the one in a higher position and envy him is a great wrong.

A human birth is very hard to attain. No other birth has an intelligence joined with such understanding and discernment. Above all, if we are to reach full growth, whether of the body, of the intellect or of the spirit, the body must be strong. For health, games and sport are essential. But this health does not belong to the body alone. Along with it, health of the mind is essential. Only when body and mind are both healthy and content can man succeed in what he has resolved. But when body and mind are not healthy as they should be, he cannot carry even a small task through to success. So for such full growth, trikaraṇa śuddhi, the purity of the three instruments, is of the first importance. The trikaraṇas are speech, hands and Manas; we must prove these three to be sacred instruments. In the Veda there are three kinds of section: the karma kāṇḍa, the upāsanā kāṇḍa, the jñāna kāṇḍa. They have been set out as the three yogas: Karma Yoga, Bhakti Yoga and Jñāna Yoga.
