sampajÄno = lucid-discerning, not "situational awareness" (B. Sujato translation), more than 'alert' (B. Thanissaro)
sampajÄno = lucid-discerning in verb form: pajÄnÄti (he discerns). See SN 54.1 , MN 10 , 3⚡š . Frequently occurs in the phrase S&Sšš sati & sampajÄno. SampajÄno is what Dhamma-vicaya 2ššµ️ (Dharma investigation) does in the 7sb☀️ awakening factors. SampajÄno is equivalent and/or closely associated with paƱƱa/discernment 5š , vimÄmsa/discrimination of 4ip š⚡ , right view 1š , vipassana/insight (see SN 46.3 ). Abhidhamma Vibhanga in this case agrees very much with the EBT suttas, that sampajano is far more than just "situational awareness". 4š☸ → Vb → Tv Ab Vb 7 Sati-'paį¹į¹hÄna-vibhaį¹
