言自性假立尋思、差別假立尋思者，觀名義等各有苦無常漏無漏等差別，差別是義，假立尋思並是從義為名，四如實得名准之可知。泰法師述本音毘恒迦，此云尋思，遮羅此云伺，菩提云覺，毘鉢舍那云觀也。基師云：其尋思如實智通二智者，如對法攝論。

Regarding 'investigation of the nominal designation of intrinsic nature' and 'investigation of the nominal designation of differentiation': one contemplates that name, referent, and so forth each have differentiations such as suffering, impermanence, taintedness, and taintlessness; 'differentiation' is the meaning, and both nominal designation and investigation are named from meaning. How the four accurate cognitions get their names may be understood by analogy. Dharma Master Tai states: The original phonetic transcription is vitarka, translated here as investigation; vicāra is translated here as reflection; bodhi is translated as awakening; vipaśyanā is translated as insight. Master Ji says: That the cognitions of investigation and accurate cognition extend to both cognitions is as stated in the Abhidharmasamuccaya and the Mahāyānasaṃgraha.
