Ascertain the sum-total of the Rasi products obtained by multiplying the figures in the several signs from Mesha onwards by their appropriate Rasi-multipliers. These for the 12 signs from Mesha onwards are 7, 10, 8, 4, 10, 5, 7, 8, 9, 5, 11 and 12. Ascertain also the sum-total of the Graha products obtained by multiplying the figures in the signs occupied by the several planets into their appropriate Graha multipliers. These for the 7 Grahas from the Sun onwards are 6, 8, 8, 5, 10, 7 and 5. Add the aggregate of Rasi products to the aggregate of Graha products. Divide the grand total by 30. If the quotient should exceed 12 years, divide it by 12 and what is left exhibits the Ayus or period of life given by the planet.
