आत्मदर्शन-उपदेशः (Ātma-darśana Upadeśa) — Mind, Senses, and the All-pervading Self
पित्र्ये राग्यहनी मास: प्रविभागस्तयो: पुनः । शुक्लो5ह: कर्मचेष्टायां कृष्ण: स्पप्नाय शर्वरी
pitrye rātryahani māsaḥ pravibhāgas tayoḥ punaḥ | śuklo 'haḥ karmaceṣṭāyāṃ kṛṣṇaḥ svapnāya śarvarī ||
ବ୍ୟାସ ବ୍ୟାଖ୍ୟା କରନ୍ତି—ପିତୃଲୋକରେ ମନୁଷ୍ୟମାନଙ୍କର ଏକ ମାସ ହେଉଛି ପିତୃମାନଙ୍କର ଏକ ଦିନ-ରାତି। ସେଠାରେ ଶୁକ୍ଳପକ୍ଷ ତାଙ୍କର ଦିନ—କର୍ମଚେଷ୍ଟା ପାଇଁ; ଏବଂ କୃଷ୍ଣପକ୍ଷ ତାଙ୍କର ରାତି—ବିଶ୍ରାମ ଓ ନିଦ୍ରା ପାଇଁ।
व्यास उवाच
Time is relative across realms: the Pitṛs experience a different day-night cycle, where a human month equals their full day and night. This frames human observances within a broader dharmic cosmos and encourages disciplined, timely performance of duties and ancestral rites.
Vyāsa is instructing about cosmological time-reckoning connected with the ancestors (Pitṛs), explaining that the bright fortnight corresponds to their active daytime and the dark fortnight to their restful night.
