सर्वद्वारेषु देहेऽस्मिन् प्रकाश उपजायते ।ज्ञानं यदा तदा विद्याद् विवृद्धं सत्त्वमित्युत ॥
sarvadvāreṣu dehe’smin prakāśa upajāyatejñānaṃ yadā tadā vidyād vivṛddhaṃ sattvamityuta
When into all the doors in the body there comes a flooding of light, a light of understanding, perception and knowledge, one should understand that there has been a great increase and uprising of the sattwic guna in the nature.
Gītā 14·11When the intelligence is alert and illumined, the senses quickened, the whole mentality satisfied and full of brightness and the nervous being calmed and filled with an illumined ease and clarity, prasāda, one should understand that there has been a great increase and uprising of the sattwic guna in the nature. For knowledge and a harmonious ease and pleasure and happiness are the characteristic results of sattwa.
