Vastu and Astrology

1. The place where the cow is tied does not produce any vastu related ill effects.
2. If there is any malefic effect of any planet, serving the cow with chapatti and jaggery calms down the malefic effect.

Remove Pollution

As the peepal tree and tulasi plant give oxygen,
similarly the cow is the only animal which purifies the air. If one spoon of
pure ghee is poured on burning cow dung (in homa) then they can produce
one-ton of pure air, therefore ghee made with cow milk is used in
sacrificial fires and havans.There is no better method to remove pollution.
