“While consuming edibles, if one faces East one’s intelligence increases, if one faces South one’s fame increases, by facing West riches increase, and by facing North one achieves the topmost benefit, liberation.” (Kurma Purana)
The Skanda Purana, in a conversation between Lord Brahma and Narada Muni, describes how devotees become liberated. One who always thinks about the Supreme Lord, who chants His holy names, whose stomach contains prasadam (food that has been offered to Lord Krsna), whose head has been touched by charanamrta (water that washed the Lord’s lotus feet), and whose body has been decorated with garlands first offered to Lord Hari-such a person has become purified equal to infallible residents of the spiritual world.
