Mythri Speaks 
Madam, everything cannot be explained to everyone. Ceratin prescriptions are written for people to follow for their good. How many of us ask reasons for each and every command that we have to follow while working with computer? Those who want to know the reson, there knowledge bank available; somtimes we may have to undergo a course of two or three years. Every one will not have the capacity or patience for that.
The same must be the case for many of the old practices. Only difference is that the ancient rules have become part of our belief system.
