This book includes the symbolism of Om and the Gayatri, the scriptural references where they are mentioned, as well a detailed instruction on how to perform the Sandhya rituals. Text for the rituals is in Sanskrit with transliteration, and English translation.
Nature, body, mind go to death, not we. We neither go nor come. The man Vivekananda is in nature, is born and dies; but the Self we see as Vivekananda is never born and never dies. It is the eternal and unchangeable Reality.
-Swami Vivekananda
