Bṛhaspati (Jupiter) is the teacher of the gods and appropriately known as “Guru.” [It’s important to note early on that Bṛhaspati is not the guru of all divinity, but stick that in your back pocket until we get around to that part of the discussion.] He represents the ether, space, the external influence, and the ability for growth. The space around allows us to expand into it, and the space within allows the world to fill us. In this way Bṛhaspati represents expansion, growth, influence, and prosperity as well as absorption, fulfillment, and attainment, whether it be related to knowledge, life, material or financial gain, happiness, or spirituality.
I bow down to Bṛhaspati, 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. – Navagraha-stotram
