• śuśrūṣavaḥ — eager listeners
  From √śru, desiderative form: 'desiring to hear.' Gauḍīyas treat śuśrūṣā as a technical limb of guru-sevā — not merely listening but listening with the wish to serve. The disciple-half of paramparā.
• pravacanam — the speaker
  From pra + √vac (to speak forth). The one designated to expound. Even among peers, paramparā requires hierarchical roles to function. Gauḍīyas insist: no two-way 'sharing' — one teaches, others receive.
• tulya-śruta-tapaḥ-śīlāḥ — whose hearing of the Vedas, austerities, and character were equal
  Compound. The three qualifications: śruta (learning), tapas (penance), śīla (character). Gauḍīyas read these as preliminary, with the fourth — bhakti — as the ripening that the chapter itself will bestow on the listeners.
• svīya-ari-madhyamāḥ — friends, enemies, and neutral parties
  Compound: sva (own) + ari (enemy) + madhyama (neutral). The threefold typology of relationships. These sages have transcended it — sama-darśana (BG 5.18, 6.29) — making them fit hearers of the highest stuti.

• With whom of equal practice do I sharpen my understanding by honest questioning?
• Where do I avoid being challenged by peers and so stay duller than I could be?

Though equally qualified, the sages chose one speaker and the rest became eager listeners — the simplest model of paramparā. Truth must be spoken by one mouth at a time and received by many ears; no committee discovers brahma-vidyā.
