If one takes shelter with God and prays to Him with great longing, God will surely listen; He will certainly make everything favourable.
(p.793, The Gospel of Sri Ramakrishna)
If you want to preach, you must also give something. Preaching is not merely lecturing to a class or explaining a book. You have to give them something. Therefore you must accumulate spiritually beforehand… And never pride yourself on your having gained control over the passions. If you do, they will at once raise their heads. Ever pray to him, ‘O lord, save me from them.’
(p.92, Spiritual Talks, Swami Turiyananda.)
