Ramayana 2.21.35

नाहं धर्ममपूर्वं ते प्रतिकूलं प्रवर्तये।पूर्वैरयमभिप्रेतो गतो मार्गोऽनुगम्यते।।2.21.35।।

nāhaṃ dharmam apūrvaṃ te pratikūlaṃ pravartaye | pūrvair ayam abhipreto gato mārgo ’nugamyate || 2.21.35 ||

I am not proposing to you some new ‘dharma’ that goes against established practice; I am following the very path approved and walked by our forebears.
