2.3.8

dharmārtha uttamaślokaṃ tantuḥ tanvan pitn yajet /
rakṣākāmaḥ puṇyajanān ojaskāmo marudgaṇān //

(8) For the promotion of the spirit of righteousness, one should worship Vishnu (the Lord of excellent fame); he who is desirous of extending his race should worship the Pitris (the gods so-called); he who wishes to provide himself with defence (against harassing troubles) should worship Punyajana (yakshas), and he who desires lasting strength should worship the group of the gods called Maruts.
