Śarīrin, Buddhi, and the Limits of Sense-Perception (इन्द्रियबुद्धिशरीरिविचारः)
तस्य तत् पूर्वसंरुद्धमात्मन: षष्ठमान्तरम् । स्फुरिष्यति समुदशभ्रान्ता विद्युदम्बुधरे यथा
tasya tat pūrvasaṃruddham ātmanaḥ ṣaṣṭham antaram | sphuriṣyati samudaśabhrāntā vidyud ambudhare yathā ||
ପୂର୍ବ ପ୍ରୟାସରେ ଇନ୍ଦ୍ରିୟସହିତ ମନ କିଛି ସମୟ ପାଇଁ ସଂଯମିତ ଓ ସ୍ଥିର ହୋଇଥିଲେ ମଧ୍ୟ, ସୁଯୋଗ ପାଇଲେ ସେ ପୁଣି ଭଡ଼କି ଉଠେ—ଯେପରି ମେଘମଧ୍ୟରେ ବିଦ୍ୟୁତ୍ ହଠାତ୍ ଚମକେ। ସେହିପରି ମନ ବାରମ୍ବାର ବିଷୟମାନଙ୍କ ଦିଗକୁ ଧାଉଁଥିବାରୁ ଚଞ୍ଚଳ ହୁଏ; ତେଣୁ ଆତ୍ମସଂଯମରେ ନିରନ୍ତର ସତର୍କତା ଓ ଅବିରତ ଅଭ୍ୟାସ ଆବଶ୍ୟକ।

Temporary restraint is not final victory: even a mind subdued by effort can surge back toward sense-objects when an opportunity arises. Therefore one must practice sustained vigilance (apramāda), repeated restraint, and steady discipline rather than trusting a brief calm.
In Bhishma’s instruction in the Śānti Parva, he explains the practical difficulty of inner governance. Using the image of lightning flashing in a cloud, he describes how the mind—counted as the ‘sixth’ alongside the five senses—can suddenly become active again after having been checked, and thus needs ongoing training.
