In the higher sense, Jupiter is the divine grace, which can fulfill all of our needs without our seeking. He gives religious merit and spiritual beneficence. The other most important aspect of Jupiter is that he gives us true knowledge and wisdom as opposed to information-based intelligence, which is the function of Mercury. The power of Mantras & Shlokas has been acknowledged since time immemorial. A Mantra can consist of a powerful word or a combination of words and can be used for self-realization, for freedom from worries, to fulfill one's desires, to ward off the effects of malefic planets, to bring you success, peace, and contentment—the range is truly vast. You can choose for yourself.

Puranic Mantra for Propitiating Jupiter

You may also opt to chant the following Puranic mantra for propitiating Jupiter (19,000 times):

Devanam ca rishinam gurun kanchana-sannibhham
buddhi-bhutam tri-lokesham tam namami brihaspatim

When translated in English, it means: "I bow down to Brihaspati, god of the planet Jupiter. He is the spiritual master of all the demigods and sages. His complexion is golden, and he is full of intelligence. He is the controlling lord of all three worlds."

Mantras must be chanted or recited with unwavering devotion and motivation. Chanting them as a matter-of-course deprives them of power and is practically useless from the point of view of conscious growth, evolution and effect.
