Bhagavad Gita
Chapter 4 · Verse 7
यदा यदा हि धर्मस्य ग्लानिर्भवति भारत। अभ्युत्थानमधर्मस्य तदात्मानं सृजाम्यहम्॥
yadā yadā hi dharmasya glānir bhavati bhārata, abhyutthānam adharmasya tadātmānaṁ sṛjāmy aham
A promise of renewal: balance that has faded doesn't stay lost. The conditions for its return keep arising, again and again.
Wherever goodness fades, the strength to restore it rises again.
