In the Vividha Yoga chapter of Bṛhat Parāśara Horā Śāstra, Parvata Yoga is formed when benefic planets occupy kendras and trikonas, while malefics are weak or placed away from these key houses. Parāśara states that this yoga bestows stability, prosperity, respect, and an elevated social standing, likening the native to a firm and enduring mountain. The yoga gives its best results when benefics are strong and unafflicted, and when supportive daśās operate.
