The Yellow Jambhala is considered the most popular and powerful of the Wealth Gods. It is thought to be the manifestation of Buddha Ratnasambhava, the Buddha of Giving. It is said you must practice Buddhism using correct procedures to gain the most powerful blessings from him. He is usually shown sitting on a lotus, sun and moon disk. As with all of the Jambhala, he holds a mongoose in his left hand which produces jewels to give to the needy.He protected the dharma and if anyone call his name, he will come and help the person. If one has trouble with finance or anything, one can chant his mantra and he will come and help. But one must have a bodhi mind and practice Buddhism properly to attain his blessings. One can also gain wealth, wisdom, intelligence and at last! Attain Buddha hood!.
The Yellow Jambhala is thought to be the most effective for those with a Chinese Astrological lucky element of earth and having the animal sign of a cow, dragon, sheep, or dog. You will receive not only wealth but wisdom and intelligence if worshipped properly. The Mantra you would recite is
"Om Zambala Zalendhraye Soha".
嗡。藏巴拉。札楞札耶。梭哈
據《大藏經》載，釋迦牟尼佛讓黃財神解說其咒功德。黃財神說其咒時，三千大千世界即發六種震動。眾不退轉菩薩及眾夜叉同聲讚歎，前未所聞，此等稀有殊勝之法。釋尊言說，此咒是痛苦無依眾生之解脫皈依處。非但持誦，僅只視咒，即不生病。持誦此咒，無有愁苦憂惱，身體疼痛不生。此咒猶如寶瓶、如意寶、如意樹，隨其所欲，滿眾生所願。若有人能持此咒者，衣食財寶多聞聰慧無病長壽，隨所願求，無不遂意，獲福甚多。無福報善根之人，無緣睹聞，乃至書寫持誦此咒。佛言，念誦此咒之人，我必攝受，入不退轉解脫之道路，得不退轉無上菩提，不墮入惡道，成為智人賢者恭敬處。此咒功德，所有神龍夜叉聚於一處，亦評說不盡；菩薩及聲聞緣覺等大智慧身，無能得知；諸佛讚說不已，亦永無盡處。此陀羅尼咒，為三世佛母。諸佛恆常加持，持此咒人，能獲六度十地之功德。(by http://www.yaoshirulai.org/Buddha/?p=622)
