"Always do your duty to others, but love you must give to God alone. Worldly love always brings in its wake untold misery."
"If you love any human being you will have to suffer for it. That person is blessed, indeed, who can love God alone. There is no suffering in loving God."
"Repeat the name of God always in the innermost core of your heart and in all sincerity take refuge in Sri Ramakrishna. Do not bother to know how your mind is reacting to things around. And do not waste time in calculating and worrying over whether or not you are progressing in the path of spirituality. It is egotism to judge progress for oneself. Have faith in the grace of your guru and God."
