सत्त्वं सुखे सञ्जयति रजः कर्मणि भारत।ज्ञानमावृत्य तु तमः प्रमादे सञ्जयत्युत।।14.9।।
Sattvam sukhe sanjayati rajah karmani bharata, gyanamavritya tu tamah pramade sanjayatyuta
Simple meaning, written by AISattva brings happiness, Rajas creates activity, and Tamas, when covered by ignorance, causes delusion.
