about placing of navgraha yantra at home in worship place

[Guest guest]

namaste guruji,

I have a question about placing the navgraha yantra and seek advice from you all

experts in astrology. Pls find below my query.

I heard somewhere that placing yantra while chanting mantra of a deity gives

faster results. If it is true then can one place navghraa yantra (all nine

planets yantra on one slide) in home in worship place and can do pooja of the

same? There are different opinions of different astrologers about the placing of

navgraha yantra in worship place at home. Some say that its not good to keep

this yantra and some say exactly opposite of it. How can one proceed to have

these yantra when all the family members are having this and that planetery

dosha and hence one requires all these yantras at home? Is there any pooja

required before placing yantras in worship place?can one keep this yantra in

personal bag and carry after puja?
