After dividing the huge Brahmâṇḍa into two parts, He (Svayambhu) made the Heaven and Earth, Âkâśa and the quarters. The upper portion of the divided Brahmâṇḍa formed the heaven, the lower one the earth. The direction in which the Sun was located was termed, purva *i.e.*, East, the direction on the right handside of Brahmâ was named dakṣina, *i.e.*, South, the direction to His left hand side was styled uttara, *i.e.*, North, and the one falling at His back came to be known as paśchima, *i.e.*, West.—32.
