धूमो रात्रिस्तथा कृष्णः षण्मासा दक्षिणायनम्।
तत्र चान्द्रमसं ज्योतिर्योगी प्राप्य निवर्तते।।8.25।।
8.25. The southern course [of the sun], consisting of six months, is smoke, night, and also dark. [Departing] in it, the Yogin attains the moons light and he returns.
8.24-25 Agnih etc. Dhumah etc. Northern : upper (or upward). Course : the one taken [by the sun] during the period of six months. This course, on account of its illuminating nature, is figuratively described by the words denoting fire etc., and the course, contrary to this, by opposite terms. This course is intercepted with the lunar parts of enjoyment. Hence [it leads to] the return for enjoyment.
