We read in the texts the following story: “On one occasion Upáli, a fervent follower of
Nigaóþha Nátaputta, the Jain, visited the Buddha, thoughtfully listened to the Dhamma,
gained saddhá (confidence based on knowledge) and forthwith manifested his readiness to
become a follower of the Master. Nevertheless, the Master said: `Of a truth, Upáli, make
thorough investigation,' and thus discouraged him.
