Meditation is central to all spiritual life, whatever be the religion one follows. Swami Ritajananda, who had wide experience with spiritual seekers both in India and abroad, has very clearly set forth the principles and practice of meditation. The part played by the guru and the mantra are lucidly set forth. Quotations are also given from the Scriptures to explain the various factors involved in meditation.
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
