सिंहोक्षाविस्रश्चतौ लिकुभाः सूर्यात्रिकोणभम् । चतुरस्रं तूर्यमृत्युत्रिकोणं नवपंचमम् ॥ १० ॥

“Lion” and “bull,” and also the “drooping/relaxed” forms, are said to belong to the fourfold type. The Sun is to be represented as a triangle; the four-sided figure is the “fourth”; and the triangle is connected with death. The ninth and the fifth are likewise to be understood accordingly.

It signals that the text sometimes teaches Dharma and Moksha using technical schemata—classifying forms and directions through symbols (triangle/square) to guide correct contemplation and ritual precision.
Indirectly: by prescribing correct symbolic forms (especially connected with Surya and mortality), it supports disciplined practice; such disciplined ritual order is presented as an aid that can be integrated into devotion rather than replacing it.
Vedanga Jyotisha/technical diagrammatics: the verse associates specific geometric figures (triangle, quadrilateral) with enumerated positions (e.g., fourth, fifth, ninth) and with themes like Surya and mṛtyu, indicating a rule-based symbolic mapping used in applied ritual/astrological instruction.
