述曰。既受得戒依經。亦須識六重八重等戒。初六重者。如依優婆塞戒經云。若優婆塞受持戒已。雖為天人乃至蟻子悉不應殺。若受戒已若口教殺若身自殺。是人即失優婆塞戒。尚不得暖法。況四沙門果。是名初重。如是不得偷盜。不得虛說我得不淨觀。不得邪婬。不得宣說四眾所有過罪。不得酤酒。若破是等戒即失優婆塞戒。尚不得暖法。況得四沙門果。是名六重。

The Commentary states: Having received the precepts in accordance with the sūtra, one must also recognize the six grave precepts, the eight grave precepts, and so forth. Regarding the first six grave precepts, as the Upāsakaśīla-sūtra says: If an upāsaka, having received and maintained the precepts, even kills a deva, a human, down to an ant, they should not do so. If after receiving the precepts they verbally instruct someone to kill or kill with their own body, that person immediately loses the upāsaka precepts; they will not even attain the heat stage, how much less the four fruits of a śramaṇa. This is called the first grave offense. Likewise, one must not steal; one must not falsely claim to have attained the meditation on impurity; one must not engage in sexual misconduct; one must not broadcast the faults and transgressions of the four assemblies; one must not sell alcohol. If one breaks these precepts, one immediately loses the upāsaka precepts; one will not even attain the heat stage, how much less the four fruits of a śramaṇa. These are called the six grave offenses.
