Guṇa-vibhāga: The Three Modes and the Path Beyond Them
यदेतरौ जयेत् सत्त्वं भास्वरं विशदं शिवम् । तदा सुखेन युज्येत धर्मज्ञानादिभि: पुमान् ॥ १३ ॥
yadetarau jayet sattvaṁ bhāsvaraṁ viśadaṁ śivam tadā sukhena yujyeta dharma-jñānādibhiḥ pumān
光り輝き、清らかで吉祥なるサットヴァがラジャスとタマスに勝って優勢となるとき、人は安楽とダルマ、知恵などの善き徳を容易に備える。
One can control one’s mind and senses in the mode of goodness.
In 11.25.13, Kṛṣṇa explains that when passion and ignorance are conquered, sattva (goodness)—clear and auspicious—naturally predominates, making dharma and spiritual knowledge arise more easily.
Kṛṣṇa is instructing Uddhava on inner purification and spiritual progress: understanding the guṇas and rising into sattva supports steady dharma and jñāna, which prepare one for devotion and transcendence.
Reduce tamas (laziness, intoxication, heedlessness) and rajas (restless craving) through clean habits, truthful living, and disciplined practice; as sattva increases, clarity, ethical strength, and spiritual understanding become easier to cultivate.
