De la propia radiancia del Sol, al transitar por las divisiones del zodíaco que comienzan con Aries, el resultado se comprende según el Lagna (ascendente): en las seis “casas” y en las otras ocho clases, y también con los factores acompañantes que empiezan por los nakṣatras; así debe determinarse el signo ascendente.

Vrata: none
Primary Rasa: shanta
Secondary Rasa: adbhuta
It frames Jyotiṣa (astral calculation) as a dharma-supporting tool: by reading time through the Sun’s course and the lagna, one aligns actions with cosmic order rather than mere impulse.
Indirectly: it supports bhakti-practice by emphasizing proper timing and order (kāla-dharma), which traditionally helps devotees perform vrata, japa, and pūjā with steadiness and discipline.
Vedāṅga Jyotiṣa—using the Sun’s movement through signs (starting with Aries) and related divisions to determine the lagna/ascendant and interpret outcomes across houses and associated factors.
