Yesterday I draw my first yantra that was a Ganesh yantra but couldn’t colour it. And my question is can we colour yantra on any day or has to be on particular thithi. Every yantra has a certain direction which has to be placed in that particular direction of the house so can we place yantra on that particular direction in bedroom and have same results. And my next question is that It is said that all the devi and devta can be invoked in shree yantra then why do we make different yantras for different gods. And can I make shree yantra and keep it in my money bag.
