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.
The less the thought of the body, the better it is. For it is the body that drags us down. It is attachment, identification which makes us miserable. That is the secret: to think that I am the spirit and not the body, and that the whole of this universe with all its relations, with all its good and all its evil, is but as a series of paintings--scenes on a canvas--of which I am the witness.
-Swami Vivekananda
