Avyakta–Vyakta and Causality: Discrimination of Field and Knower
अस्पर्शनमशृण्वानमनास्वादमदर्शनम् । अप्राणमवितर्क च सत्त्वं प्रविशते परम्
asparśanam aśṛṇvānamanāsvādam adarśanam | aprāṇam avitarkaṃ ca sattvaṃ praviśate param, parabrahma paramātmā sparśa-śravaṇa-rasana-darśana-prāṇa-saṅkalpa-vikalpa-se bhī rahita hai; isaliye kevala viśuddha buddhi hī usameṃ praviśa kar pātī hai |
ビーシュマは説く。「至上の実在—パラム・ブラフマン、パラマートマン—は、触・聞・味・見の及ぶところを超え、また呼吸の常の働きや分別の思惟をも超越している。ゆえに、感官の騒ぎと心の揺らぎを離れた、清浄で澄明な知（サットヴァ／シュッダ・ブッディ）のみが、その最高原理へ入り、これを体得しうる。」
भीष्म उवाच
Educational Q&A
The Supreme (Parabrahman/Paramatman) is not an object of the senses or of discursive thought; realization requires a purified, sattvic intellect that is free from sensory dependence and from saṅkalpa–vikalpa (mental wavering).
In the Shanti Parva’s instruction on liberation and right understanding, Bhishma continues advising Yudhishthira by describing the transcendence of the Supreme Self and the inner discipline—purification of mind/intellect—needed to realize it.
