[C]ontinence is a very important part of yoga. If a handful of people come forward with strong wills, nothing is impossible. One Buddha changed half the globe; one Jesus, three quarters of the world. We all have that capacity. (140)

Everything begins in the mind. If you want to see clearly, you need clear vision.

The five points of yama, together with the five points of niyama, remind us of the Ten Commandments of the Christtian and Jewish faiths, as well as of the ten virtues of Buddhism. In fact, there is no religion without these moral or ethical codes. All spiritual life should be based on these things. They are the foundation stones without which we can never build anything lasting. (127)

[O]ur own bodies are changing every second. Yet we take the body to be our Self; and, speaking in terms of it, we say, “I am hungry” or “I am lame”; “I am black” or “I am white.” These are all just the conditions of the body. We touch the truth when we say, “My body aches,” implying the body belongs to us and that therefore we are not that. (87)

The same thing can be both good and bad. Whenever you speak of good, bad is also present. The world is a mixture of both. There is not good without bad. They are both sides of the same coin. Both are necessary. We have been given free will and discriminating capacity to select what is beneficial to us and to avoid what is detrimental to us. Even Cobra poison can be used as medicine.

We are not going to change the whole world, but we can change ourselves and feel free as birds. We can be serene even in the midst of calamities and, by our serenity, make others more tranquil. Serenity is contagious. If we smile at someone, he or she will smile back. And a smile costs nothing. We should plague everyone with joy. If we are to die in a minute, why not die happily, laughing? (136-137)

Anything that you throw comes back. All your actions are echoes.
