When the paka of a planet in the dasa, antardasa, etc. of another planet is required, multiply the number representing the years of the mahadasa of the former into the figure denoting the years, months, days etc. of the latter and divide the product by the fixed number of years for the maximum Ayus. The quotient will be the paka required. This rule is to be applied in the case of every paka that has to be found.
