In plain words
Who is your master. Your conscience is your master, guru and God. Follow your conscience. 2nd F face the devil. Do not be afraid in the least of evil qualities and evil thoughts. 3rd F fight to the end. 4th F, finish the game. That is, properly complete the task you have taken up. Come what may, you must set about achieving it through perseverance.
Whatever you have held, you have held fast: stay so till your hold prevails. Whatever you have wished for, you have wished indeed: keep on worshipping till your wish is fulfilled. Whatever you have asked, you have asked indeed: do not let go till what you asked is given. Whatever you have thought of, you have thought indeed: do not stir till your thought is fulfilled. Unable to bear your pressing, He Himself must save you; or, forgetting the body, you yourself must ask. Other than this, … turning back and going away is not the vow of a devotee.
That is dīkṣā: determination. Perseverance. On what must that perseverance be set? This perseverance must be set on what is sacred, on whatever has to do with helping others. Help ever, hurt never. Students must hold fast to things of this kind with perseverance. For this they must win the right friendship. Who is that friend? God Himself. God alone is the true friend. The hand that helps in every task, with no wish for reward, hoping for nothing, asking for nothing, is God's. Always a helping hand. Such help is what we must ask for.
One day all the deer of a forest gathered and held a conference. At this conference, it seems, the president of the deer made a proposal. "Beloved deer! In what are we less than dogs? The dogs have nothing like our running. In strength and ability we are not less than dogs. Dogs cannot leap as high as we can. They cannot run as far as we can. Ours is sāttvic food. Theirs is tāmasic food.
