We must recognise that duty and morality vary under different circumstances; not that the man who resists evil is doing what is always and in itself wrong, but that in the different circumstances in which he is placed it may become even his duty to resist evil.
Swami VivekanandaWhen the body is still healthy and diseaseless, When old age has not yet attacked it
Swami VivekanandaThat intense faith in another world, that intense hatred for this world, that intense power of renunciation, that intense faith in God, that intense faith in the immortal soul, is in you. I challenge anyone to give it up. You cannot. You may try to impose upon me by becoming materialists, by talking materialism for a few months, but I know what you are; if I take you by the hand, back you come as good theists as ever were born. How can you change your nature?
Swami Vivekananda
