How should the three lines be applied, Jabali is asked. The text states in verse 22, the three lines should occupy all of the forehead. The three lines signify the trimurti of Brahma, Vishnu and Shiva. The top line represents Garhapathya agni or home fire, syllable Aa of AUM, one's own body (self), Rajas guna, the power to act, the Rigveda, ushakala (twilight hour) or early morning hour, and is the personification of Brahma. The second streak or the middle line denotes Dakshinagni, syllable Uu of AUM, Sattva Guṇa (virtue), atman (soul, innermost self), the power to will, Yajurveda, midday, and is the personification of Vishnu. The third streak of bhasma or ash line represents the Ahavaniya agni, the syllable Ma of AUM, the Supreme Self (Brahman), the power to know, the heavens, Tamas guna, Samaveda, evening time, and is personified by Shiva.
