The Mahābhārata sums up Sanātana Dharma (Hinduism) as:–
adrohaḥ sarvabhūteṣu karmaṇā manasā girā |
anugrahaśca dānaṃ ca stāṃ dharma sanātanaḥ ||
The Eternal Duty (Sanātana Dharma) towards all creatures is the absence of malevolence towards them in thought, deed or word, and to practice compassion and generosity towards them. (MB Vana Parva 297;35)
