When the state of Rajas is awakened, the Understanding becomes changed into Rajas. Delight, joy, gladness, happiness, and contentment, these when somehow excited, are the properties of Sattva. Heart-burning, grief, sorrow, discontentment, and unforgiveness, arising from particular causes, are the outcome of Rajas. Ignorance, attachment and mistake, carelessness, stupefaction, and terror, meanness, cheerlessness. sleep and procrastination,-these, when engendered by particular causes, are the properties of Tamas.
प्रवर्तमानं तु रजस्तद्भावेनानुवर्तते। प्रहर्षः प्रीतिरानन्दः सुखं संशान्तचित्तता॥ कथंचिदुपपद्यन्ते पुरुषे सात्त्विका गुणाः। परिदाहस्तथा शोकः संतापोऽपूर्तिरक्षमा॥ लिङ्गानि रजसस्तानि दृश्यन्ते हेत्वहेतुभिः। अविद्या रागमोहौ च प्रमादः स्तब्धता भयम्॥ असमृद्धिस्तथा दैन्यं प्रमोहः स्वप्नतन्द्रिता। कथंचिदुपवर्तन्ते विविधास्तामसा गुणाः॥
