Mere philosophy will not satisfy us. We cannot reach the goal by mere words alone. Without practice, nothing can be achieved. (3)

If you have done something meritorious, you experience pleasure and happiness; if wrong things, suffering. A happy or unhappy life is your own creation. Nobody else is responsible.

There’s no value in digging shallow wells in a hundred places. Decide on one place and dig deep. Even if you encounter a rock, use dynamite and keep going down. If you leave that to dig another well, all the first effort is wasted and there is no proof you won’t hit rock again. (52)
These Sutras are reminiscent of the Four Noble Truths of Lord Buddha: the misery of the world, the cause of misery, the removal of that misery, and the method used to remove it. Patanjali tells us that pain can be avoided. He further tells us that its cause is ignorance. (115)
It's very simple. Keep your body as clean as possible, your mind as clear as possible. That's all you need. And do it in anyway you can, in your own way. It doesn't matter.
