Skanda Purana — Nagara Khanda, Shloka 21
तत्किं ते तपसः शक्त्या ब्राह्मणस्य विचक्षण । अपरं शृणु मे वाक्यं यद्ब्रवीमि परिस्फुटम् । शृण्वतां मुनिवृन्दानां तथान्येषां द्विजोत्तम
tatkiṃ te tapasaḥ śaktyā brāhmaṇasya vicakṣaṇa | aparaṃ śṛṇu me vākyaṃ yadbravīmi parisphuṭam | śṛṇvatāṃ munivṛndānāṃ tathānyeṣāṃ dvijottama
「見識ある婆羅門よ、汝の苦行の力は何の役に立つのか。今、我が別の言葉を聞け。私はそれを明白に語ろう――聖仙の群れと他の者たちが聞き入るこの場で、二度生まれの最勝者よ。」
Triśaṅku (continued address to Vasiṣṭha)
Listener: Vasiṣṭha (and implicitly the assembled sages)
Scene: Triśaṅku speaks loudly, turning slightly toward the gathered sages as if to shame Vasiṣṭha; Vasiṣṭha remains composed; sages react with mixed concern and silence.
