varga uttama sva parageṣu śubhaṃ yad uktaṃ tat puṣṭa madhya laghutā śubham utkrameṇa/
vīrya anvito aṃśaka patir niruṇaddhi pūrvaṃ rāśī kṣaṇasya phalam aṃśa phalaṃ dadāti//(va ti)E19

The good that has been declared in vargottama, one's own, and another's [navāṃśa] is full, medium, and slight respectively, and the bad in reverse order. / When endowed with strength, the ruler of the navāṃśa checks the prior result of the aspect upon the sign and gives the result of the navāṃśa.
