Chapter 2, Verse 45
Part of 2: Sānkhya Yog — सांख्ययोगत्रैगुण्यविषया वेदा निस्त्रैगुण्यो भवार्जुन। निर्द्वन्द्वो नित्यसत्त्वस्थो निर्योगक्षेम आत्मवान्॥
trai-guṇya-viṣhayā vedā nistrai-guṇyo bhavārjuna nirdvandvo nitya-sattva-stho niryoga-kṣhema ātmavān
The Vedas deal with the three attributes; be thou above these three attributes. O Arjuna, free yourself from the pairs of opposites and ever remain in the quality of Sattva, freed from acquisition and preservation, and be established in the Self.
Guna means attribute or ality. It is substance as well as ality. Nature (Prakriti) is made up of three Gunas, viz.? Sattva (purity, light or harmony)? Rajas (passion or motion) and Tamas (darkness or inertia). The pairs of opposites are heat and cold, pleasure and pain, gain and loss, victory and defeat, honour and dishonour, praise and censure. He who is anxious about new acuqisitions or about the preservation of his old possessions cannot have peace of mind. He is ever restless. He cannot concentrate or meditate on the Self. He cannot practise virtue. Therefore? Lord Krishna advises Arjuna that he should be free from the thought of acisition and preservation of things. (Cf. IX.20?21).
