Avyakta–Vyakta and Causality: Discrimination of Field and Knower
मनस्याकृतयो मग्ना मनस्त्वभिगतं मतिम् | मतिस्त्वभिगता ज्ञानं ज्ञानं चाभिगतं परम्,मनमें शब्दादि विषयरूप समस्त आकृतियोंका लय होता है। मनका बुद्धिमें, बुद्धिका ज्ञानमें और ज्ञानका परमात्मामें लय होता है
manasy ākṛtayo magnā manas tv abhigataṃ matim | matis tv abhigatā jñānaṃ jñānaṃ cābhigataṃ param ||
मनस्याकृतयो मग्ना मनस्त्वभिगतं मतिम् । मतिस्त्वभिगता ज्ञानं ज्ञानं चाभिगतं परम् ॥

Educational Q&A
It teaches a graded inner dissolution (laya): sensory forms and mental impressions resolve into mind; mind resolves into intellect; intellect resolves into liberating knowledge; and that knowledge culminates in absorption into the Supreme. The ethical thrust is that mastery of the inner faculties—rather than outer conquest—leads to peace and final freedom.
In Shanti Parva, Bhishma instructs Yudhishthira on dharma and the path to peace after the war. Here he shifts to a contemplative, moksha-oriented teaching, describing how a seeker withdraws from sense-objects and progressively integrates the inner faculties until realization of the Supreme.
