This is known as the Sarvopari Yantra; Sarvopaari translated into plain English means Paramount or Excellent. Hence this is one of the many Yantras for success in every kind of work; be it for any purpose.
The Yantra has to be drawn on a Bhojpatra, using Kesar [Saffron] water, in the early part of the morning, after having your bath and wearing clean clothes. Then it has to be worshipped to energize it and a scented incense stick has to be lit in front of it.
After completing the above Sadhana, it must be put in a Silver Locket and tied as an amulet around the neck as a luck bringing charm.
