धूमो रात्रिस्तथा कृष्णः षण्मासा दक्षिणायनम् | तत्र चान्द्रमसं ज्योतिर्योगी प्राप्य निवर्तते
dhūmo rātristathā kṛṣṇaḥ ṣaṇmāsā dakṣiṇāyanam . tatra cāndramasaṃ jyotiryogī prāpya nivartate
烟、夜晚、以及亏月和太阳南行期的六个月——遵循这条道路，瑜伽士抵达月光后，便会返回。
Smoke, night, as also the dark fortnight and the six months of the Southern solstice-following this Path the yogi having reached the lunar light, returns.
这是祖先道（Pitriyana），即黑暗之路或祖先之路，它导致转生。那些为了回报而向众神献祭并从事其他慈善工作的人，通过这条道路前往月亮界（Chandraloka），当业（Karma）的果报耗尽时，他们便会返回这个世界。烟、夜晚、亏月和太阳南行期的六个月，都代表着掌管它们的神祇。它们可能也象征着无明、执着和欲望的程度。这条道路上充满了烟雾和黑暗之物，行经此路时没有启蒙，它是由无明所达到的，因此被称为黑暗之路或烟雾之路。
This is the Pitriyana or the path of darkness or the path of the ancestors which leads to rirth. Those who do sacrifices to the gods and other charitable works with expectation of reward go to the Chandraloka through this path and come back to this world when the fruits of the Karmas are exhausted.Smoke? night time? the dark fortnight and the six months of the southern solstice are all deities who preside over them. They may denote the degree of ignorance? attachment and passion. There are smoke and darkcoloured objects throughout the course. There is no illumination when one passes along this path. It is reached by ignorance. Hence it is called the path of darkness or smoke.
