Skanda Purana — Mahesvara Khanda, Shloka 70
राजसैस्तामसैश्चैव योगी सिद्धयेन्न कर्हिचित् । श्रद्दधानेषु दांतेषु श्रोत्रियेषु महात्मसु
rājasaistāmasaiścaiva yogī siddhayenna karhicit | śraddadhāneṣu dāṃteṣu śrotriyeṣu mahātmasu
Sa mga paraang rājasika at tāmasika, hindi kailanman makakamit ng yogi ang kasakdalan. Sa halip, dapat siyang umasa at makisama sa mga may pananampalataya, may pagpipigil-sa-sarili, bihasa sa Veda, at dakila ang loob.

Scene: A yogin turns away from noisy, indulgent company and approaches a small assembly of calm, Veda-chanting elders; the contrast of rajas/tamas vs sattva is shown through color and posture.
