śramaṇa
Śramaṇa and Bhikshu are synonyms, both appellations for fully ordained Buddhist monks. The Buddha was also called ‘the great śramaṇa.’

Commentary

Those who take leave of their families and go forth from the home-life, who recognize their minds and penetrate to their origin, and who understand the unconditioned Dharma, are called śramaṇas.

Constantly observing the 250 precepts, they enter into and abide in purity. By practicing the four true paths [i.e., Four Holy Truths] they become Arhats. (S42 1)
