Bhṛgu–Bharadvāja-saṃvāda: Vānaprastha-parivrājaka-ācāra, Abhaya-dharma, and Lokānāṃ Vibhāga (Śānti-parva 185)
ऊष्मतो म्लायते पर्ण त्वक् फल॑ पुष्पमेव च । म्लायते शीर्यते चापि स्पर्शस्तेनात्र विद्यते
Ūṣmato mlāyate parṇa tvak phalaṁ puṣpam eva ca | mlāyate śīryate cāpi sparśas tenātra vidyate ||
ଭରଦ୍ୱାଜ କହିଲେ—ବୃକ୍ଷର ଭିତରେ ଥିବା ଉଷ୍ମାରେ ତାହାର ପତ୍ର, ଛାଲ, ଫଳ ଓ ପୁଷ୍ପ ମ୍ଲାନ ହୁଏ; ମ୍ଲାନ ହୋଇ ଶେଷେ ଝଡ଼ି ପଡ଼େ। ଏହାଦ୍ୱାରା ବୃକ୍ଷରେ ସ୍ପର୍ଶେନ୍ଦ୍ରିୟ ଥିବା ମଧ୍ୟ ସିଦ୍ଧ ହୁଏ।
भरद्वाज उवाच
The verse argues by observable signs (withering and shedding due to internal heat) that a tree is capable of tactile sensation (sparśa). It supports an ethical-philosophical view that living beings may possess subtle forms of sensation, encouraging careful conduct toward them.
In a Shānti Parva discussion framed as instruction, Bharadvāja presents a reasoned example from nature: heat affects a tree’s parts, causing withering and falling, and he uses this as evidence to establish the presence of touch in trees.
