ṢAṢṬIĀṀŚA (1/60th part of a sign or half-a-degree each): To calculate the Ṣaṣṭiāṁśa lord, ignore the sign position of a planet and take the degrees etc. it traversed in that sign. Multiply that figure by 2 and divide the degrees by 12. Add 1 to the remainder which will indicate the sign in which the Ṣaṣṭiāṁśa falls. The lord of that sign is the planet ruling the said Ṣaṣṭiāṁśa. In odd signs, the 60 Ṣaṣṭiāṁśa names are (with benefic [B] or malefic [M] character): 1. Ghora (M), 2. Rākṣasa (M), 3. Deva (B), 4.
