Push on with the organization. Nothing else is necessary but these — love, sincerity, and patience. What is life but growth, i.e. expansion, i.e. love? Therefore all love is life, it is the only law of life; all selfishness is death, and this is true here or hereafter. It is life to do good, it is death not to do good to others. Ninety per cent of human brutes you see are dead, are ghosts — for none lives, my boys, but he who loves. Feel, my children, feel; feel for the poor, the ignorant, the downtrodden; feel till the heart stops and the brain reels and you think you will go mad — then pour the soul out at the feet of the Lord, and then will come power, help, and indomitable energy.
