Jyotiṣa-śāstra Saṅgraha: Threefold Division, Gaṇita Methods, Muhūrta, and Planetary Reckoning
इष्टैः पलैस्तदूनाढ्यं व्यगावूनेऽर्कषङ्गुणः । तदन्यथाधिके तस्मिन्नेवं स्पष्टे सुखांत्यगे ॥ १५७ ॥
iṣṭaiḥ palaistadūnāḍhyaṃ vyagāvūne'rkaṣaṅguṇaḥ | tadanyathādhike tasminnevaṃ spaṣṭe sukhāṃtyage || 157 ||
When the prescribed number of palas is deficient or excessive, the result becomes correspondingly defective; and when the deficiency amounts to one vyagāva, the result is multiplied by the Sun’s factor of six.
