8.23

eka grahasya sadṛśe phalayor virodhe/nāśaṃ vaded yad adhikaṃ paripacyate tat/
na anyo grahaḥ sadṛśam anya phalaṃ hinasti/svāṃ svāṃ daśām upagatāḥ sa phala pradā syuḥ//(vasantatilakā)E8

When there is conflict between equal results of a single planet, one should pronounce the destruction [of both]; that which is greater ripens.
Another planet does not destroy an equal result of another planet; arriving at their own respective periods, they become givers of their results.
