Do your duties in the world, and also fix your mind on the Lotus Feet of the Lord. Read books of devotion like the Bhagavata or the life of Chaitanya when you are alone and have nothing else to do.
(p.281, The Gospel of Sri Ramakrishna)
We are the sons of Light and children of God. Glory unto the Lord, we will succeed. Hundreds will fall in the struggle; hundreds will be ready to take it up. …Life is nothing, death is nothing, hunger nothing, cold nothing. Do not look back to see who falls – forward – onward! Thus and thus we shall go on, brethren. One falls, and another takes up the work.
(CW, Vol.5, p.17, Swamiji’s letter to Alasinga on 20 August, 1893)
