Dr. Parthasarathy prides in basing his teachings in authentic shastras and also in explaining the basic principles rather than giving pre-built commandments which attain a life of their own and become static in nature. These commandments invariably become irrelevant or worse counter productive with passage of time and change in context. Through Dr. Parthasarathy teachings however, once you understand the basic principles it is possible for you to build your own recommendations based on first principles and therefore be able to modify these based on context be it demography, geography, weather condition, individual composition etc.
