四分律比丘含注戒本 2.573

2.573

The Buddha was in Śrāvastī. The group of seventeen said to the group of six, "How does one enter the first dhyāna?" up to "How does one attain the fruit of an arhat?" [The group of six] replied, "What you have spoken already constitutes an offense of pārājika." They went to other bhikṣus and inquired of them; [the other bhikṣus] then rebuked [the group of six], and the Buddha accordingly laid down the precept.
