इत्युक्त्वा स तदा पुत्र तत्रैवान्तरधीयत । तस्मिन्नन्तर्हिते चाहमुपांशुव्रतमाचरम्
ity uktvā sa tadā putra tatraivāntaradhīyata | tasminn antarhite cāham upāṃśu-vratam ācaram ||
Nachdem er so gesprochen hatte, mein Sohn, verschwand er sogleich an eben jener Stelle. Und als er entschwunden war, nahm ich das Gelübde des Schweigens und der inneren Rezitation auf mich und übte im Verborgenen Zügelung und Selbstdisziplin.
वायुदेव उवाच
The verse highlights disciplined restraint after receiving instruction: when the teacher or divine presence withdraws, one should internalize the teaching through a vow—here, upāṃśu-vrata—emphasizing quiet self-control and sustained practice rather than outward display.
Vāyudeva says that after someone finished speaking, that figure vanished on the spot. In response to this disappearance, Vāyudeva himself undertook an observance called upāṃśu-vrata, a practice associated with subdued or inward recitation and austerity.
