यदा यदा हि धर्मस्य ग्लानिर्भवति भारत।
अभ्युत्थानमधर्मस्य तदात्मानं सृजाम्यहम् ॥

परित्राणाय साधूनां विनाशाय च दुष्कृताम् ।
धर्मसंस्थापनार्थाय सम्भवामि युगे युगे ॥

Whenever there is decay of righteousness, O Bharata, And there is exaltation of unrighteousness, then I Myself come forth ; For the protection of the good, for the destruction of evil-doers, For the sake of firmly establishing righteousness, I am born from age to age.
