Some general information on Wealth Vases
taken from http://fourgates.com/blog/medicine-buddha-health-wealth-vases/
The origin of Health and Wealth Vases comes to us from the highly realized 10th century Indian saint and Buddhist Master, Atisha. He was taught about these from Mother Tara and other enlightened sources who guided him to relieve poverty, non-virtue and material difficulties through the power of blessings contained in the consecrated vases.
The Indian saint Atisha traveled to Tibet from India. What he found was that Tibet was a harsh, barren land with a great deal of poverty. Life was difficult for Tibetans. Atisha was inspired by his kindness and compassion to create spiritual magnetism for the people of Tibet through the blessings of health and wealth vases.
The outer manifestation of the Wealth Treasure Vase is as a vessel containing various precious substances, such as, gold, silver, semi-precious stones, shells, and turquoise. Wealth Vases also contain grains, such as, peas, lentils, rice and all kinds of good things that beings like. It has pictures and mantras of a wealth deity, and it contains a small image of sacred deities. The five elements, five colors and five Enlightened Buddha energies are represented in the creation of the consecrated vase.
These vases are made following very specific ritual instructions and with precious items. This may include relics from high Lamas and the five natural elements.
While the Wealth Vase is being filled, monks recite prayers over the vases. Once completed, a large prayer session is conducted to invoke the energies of that particular Buddha and/or wealth Buddhas, such as Dzambala. Then the vases are sealed.
Wealth Vases can be kept in your sacred space in your house, or in shrine room. However, do not store them in the bathroom. It is best to place the Medicine Buddha Health Vase at your place of business, in a office or anywhere that is clean and special to you. However, they should not be touched with bare hands and it would be best to put them in a casing, in a safe place.
