Contentment is the only viable formula, which can give everyone peace and tranquillity.

 Our lifespan being so very short, we cannot afford the luxury of wasting time and energy; we have to be very prudent. 

 A person is born under the laws of nature, but after birth the development of his personality lies in his own hands.

Everything around us, big or small, has a material content as well as a spiritual content. We have to dematerialize these things in order to extract the spiritual content.
