Gayatri mantra is a Vedic prayer. It is a universal prayer that can be used by any person, belonging to any country, irrespective of race, religion, or sex. 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.
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
