In the brilliant lecture which comprises this book the author stresses on the need to make our spiritual life all-comprehensive. Spirituality should not be narrowed down to morning and evening prayer sessions alone. True spirituality encompasses the whole gamut of human life, our every movement, our every breath. The author shows us the different ways to attain such a totally spiritualized life.
Seek ye first the kingdom of God, and everything shall be added unto you. This is the one great duty, this is renunciation. Live for an ideal, and leave no place in the mind for anything else. Let us put forth all our energies to acquire that which never fails--our spiritual perfection. If we have true yearning for realization, we must struggle, and through struggle growth will come. We shall make mistakes, but they may be angels unawares.
-Swami Vivekananda
