Bhṛgu–Bharadvāja-saṃvāda: Vānaprastha-parivrājaka-ācāra, Abhaya-dharma, and Lokānāṃ Vibhāga (Śānti-parva 185)
वक्त्रेणोत्पलनालेन यथोर्ध्व जलमाददेत् । तथा पवनसंयुक्त: पादैः: पिबति पादप:,जैसे मनुष्य कमलकी नाल मुँहमें लगाकर उसके द्वारा ऊपरको जल खींचता है, उसी तरह वायुकी सहायतासे युक्त वृक्ष अपनी जड़ोंद्वारा ऊपरकी ओर पानी खींचता है
vaktreṇotpalanālena yathordhvaṁ jalam ādadet | tathā pavanasaṁyuktaḥ pādaiḥ pibati pādapaḥ ||
قال بهاردفاجا: «كما أن الإنسان إذا وضع ساقَ اللوتس على فمه جذب الماءَ صعودًا من خلاله، كذلك الشجرة—بمعونة الريح المتحركة—تشرب الماء وتسترفعه إلى أعلى بواسطة جذورها».
भरद्वाज उवाच
The verse teaches through analogy that hidden mechanisms and supporting conditions enable visible outcomes: as a lotus-stalk can serve as a conduit to draw water upward, a tree draws water upward through its roots with the aid of wind/air. It encourages attentive reasoning about causes that are not immediately seen.
Bharadvāja is explaining a natural process in a didactic discussion: how a tree ‘drinks’ and lifts water upward. He illustrates it with a simple, observable example—sucking water through a lotus-stalk—so the listener can grasp the principle.
