Life has meaning only in the struggle. Triumph or defeat is in the hands of the gods. So let us celebrate the struggle.
Each man is a microcosm of the universe. Your body is made of all the elements of the world. Nature supplied all the ingredients that make your body, which means that the universe made you by donating itself. You could accurately say that you are a small walking universe that can move, whereas the cosmic universe is stationary.
A generous heart, kind speech, and a life of service and compassion are the things which renew humanity.
As long as you have attachment to the body and attachment to objects, fear and suffering will be with you. Therefore Krishna told Arjuna to develop his discrimination and rid himself of body consciousness. Only then he would be able to develop integral vision.
Meditating on the lotus of your heart, in the centre is the untainted, the exquisitely pure, clear and sorrowless, the inconceivable, the unmanifest, of infinite form, blissful, tranquil, immortal, the womb of Brahma.
