Mangal Dan Yantra is made with 5.5 rt of Red Coral affixed in copper. This Mangal Dan Yantra is dipped in a copper bowl containing pure Ghee on Tuesday morning then on next Tuesday before 12 noon the Yantra, copper bowl, sindur made out of crushed stones, channa dal are wrapped in 1.25 metres of orange cloth and immersed in running Holy water. This Dan is said to reduce the evil effects of Mangal and brings good results for people with mangal dosh in their or their spouse’s horoscope. It reduces the malefic results of Mangal in its dasha, antardasha or transit. This is also said to increase the fortunes of people who have faith in Hanumanji.
There is an ancient Hindu tradition that donations are given in Holy running water to ward off the evil effects of malefic planets. the ancient puranas like Agnipurana and Matsya purana deal with the donations of Rattan Jadhit Yantra (Gem studded yantra) to ward of evil and propitiate good in life. If regularly done especially near's birthday and then repeated quarterly this brings excellent results. These donations have to be made in such manner that you donate five articles at a time. This is known as PANCH MAHADAN. (The Gems used for making these Yantras are not of very high quality but original.)
These Yantras have been empowered with special Vedic mantras and Yogic Pran Pratishta by Sh. Pankaj Khanna himself.
Yantra is the Sanskrit word which means an instrument or a machine. In Tantric texts and Bhramanical Texts it means Visual Mantras or in easy words mantras made in geometrical figures and colours to influence the environment, cosmic forces, spirits around us, the evil eye of our enemies and our own aura and mental makeup. In Hindu and Buddhist mysticism this kind of geometric forms known as Yantra in Hindus and Thangka Paintings or simply Thangka in Buddhist areas is widely seen in Temples, monasteries, Homes and Viharas.
