धर्म एव हतो हन्ति धर्मो रक्षति रक्षितः ।
तस्माद्धर्मो न हन्तव्यो मा नो धर्मो हतोऽवधीत् ॥

dharma eva hato hanti dharmo rakṣati rakṣitaḥ |
tasmāddharmo na hantavyo mā no dharmo hato'vadhīt ||

Dharma only destroys (those) that destroy it. Dharma protects those who protect it. Hence, dharma should not be destroyed. Know that, ‘dharma that is destroyed, destroys!’
