As human beings, our greatness lies not so much in being able to remake the world - that is the myth of the atomic age - as in being able to remake ourselves.
Some men turn every quality or art into a means of making money; this they conceive to be the end, and to the promotion of the end all things must contribute.
Neither numbers nor powers nor wealth nor learning nor eloquence nor anything else will prevail, but purity, living the life, in one word, anubhuti, realisation. Let there be a dozen such lion-souls in each country, lions who have broken their own bonds, who have touched the Infinite, whose whole soul is gone to Brahman, who care neither for wealth nor power nor fame, and these will be enough to shake the world.
We should reflect on the idea that since the beginning of time sentient beings have been mentally unstable because they have been slaves of delusion, they lack the eye of wisdom to see the path leading to nirvana and enlightenment, and they lack the necessary guidance of a spiritual teacher. Moment by moment they are indulging in negative actions, which will eventually bring about their downfall.
It is better to do one's own duty, however defective it may be, than to follow the duty of another, however well one may perform it. He who does his duty as his own nature reveals it, never sins.
If I am only happy for myself, many fewer chances for happiness. If I am happy when good things happen to other people, billions more chances to be happy!
