“Sattva attaches to happiness, Rajas to action, O Arjuna, while Tamas, verily shrouding knowledge, attaches to heedlessness.”
14.9 सत्त्वम् purity? सुखे to happiness? सञ्जयति attaches? रजः active force? कर्मणि to action? भारत O Bharata? ज्ञानम् knowledge? आवृत्य shrouding? तु verily? तमः inertia? प्रमादे to heedlessness? सञ्जयति attaches? उत but.Commentary Just as a dark cloud enshrouds the sun? so also Tamas envelops knowledge or the light of the Self. Tamas creates an attachment for heedlessness? that is? ignorance or forgetfulness of duty or the nonperformance of necessary (obligatory) duties.
Reflect on Bhagavad Gita 14.9: Sattva attaches to happiness, Rajas to action, O Arjuna, while Tamas, verily shrouding knowledge, attaches to heedlessness.
