In Brihat Parashara Hora Shastra, the sage Parashara illustrates the nature of the 1st lord in the 9th house by stating that it inclines one to become a “Vishnu devotee.” I will now explain what he is talking about.
The Vedic pantheon contains many gods. There are two reason why: (1) There are many powers in nature, thus many gods, and (2) There are many different people who need different things from religion. Most of the gods have specific roles, rather like sanctified stores in the shopping mall of religion. If you need x,y,z go to God #34, if you need a,b,c go to God #28, etc. The head among the gods are Vishnu, Shiva, and Brahma. Brahma is not quite on the same level as the other two because he, like the other gods, is an ordinary being invested with the power to act as a god. Vishnu and Shiva, on the other hand are directly Godhead. So these two are well known as the cheif Gods of the Vedic pantheon. Shiva has the responsibility of destroying things – ultimately the entire universe; while Vishnu takes charge of preserving the universe and its components.
The 1st lord in the 9th house increases ones interest in being moral, which in some form or another is “religion.” In a sense, the 1st lord in the 9th house – on it’s own, in isolation from other factors in your horoscope – is a symbol of the pinnacle of morality and religiousity. The author illustrates this by pointing specifically to Vishnu specifically because he, following the standard classical Vedic conclusion, considered Vishnu-centered religion the topmost evolution of morality. Why? Because it is the least selfish. After all, selfishness is the antithesis of morality! So it is very logical that the gods whose function is to fulfill desires, etc. are subordinate to the Godhead who is worshipped for the sake of morality alone.
Actually, the author does not merely point to “Vishnu-religion.” He points to a “Vishnu devotee.” This refers specifically to the Vedic spiritual path of bhakti. Bhakti is the root of all spiritual paths because it is the essence of all morality – love.
By illustrating the 1st lord in the 9th house with the image of a Vishnu devotee, the author means to communicate that this placement makes one truly moral, truly religious. It decreases the interest in religious pretention or secterian badge-wearing and increases the interest of being at the heart of what morality and religion really is all about: serving others and loving the divine.
