Shloka 15
पूतात्मा परमात्मा च मुक्तानां परमा गति: । अव्यय: पुरुष: साक्षी क्षेत्रज्ञो5क्षर एव च
pūtātmā paramātmā ca muktānāṁ paramā gatiḥ | avyayaḥ puruṣaḥ sākṣī kṣetrajño 'kṣara eva ca ||
毗湿摩说道：祂是清净之我，亦是至上之我；对解脱者而言，祂是最高归趣。祂不坏不灭——住于身中的普鲁沙（Puruṣa）——恒为见证者。祂是“田”（身与自然）之知者（Kṣetrajña），亦即不衰之阿克沙罗（Akṣara）。

Educational Q&A
The verse identifies the highest reality as the pure and supreme Self—imperishable, the inner Person, the witnessing consciousness, and the knower of the body-field—teaching that liberation culminates in realizing and attaining this Supreme Self as the ultimate goal.
In Anuśāsana Parva, Bhīṣma continues his post-war instruction on dharma and higher wisdom, describing the nature of the Supreme Self to guide the listener toward ethical living grounded in self-knowledge and the pursuit of liberation.
