Yantras are of many types and you will notice that each one of the astrologer or vedic sites provide their own versions of the same yantra. It is advised to be aware of what methods are used to energize the yantra. The real significance of a yantra lies only in its energizing process.
At Parihara.com, we use only wearable type yantras, made of silver and energised individually for your name and rasi for a minimum of 45 days before it is sent to the customer. This is the recommended practice as per vedic scriptures.
