महाभारत - आदि - धर्म

आदित्यचन्द्रावनिलौ च
    द्यौर्भूमिरापो हृदयं यमश्च ।
अहश्च रात्रिश्च उभे च सन्ध्ये
    धर्मश्च जानाति नरस्य वृत्तम् ॥

- महाभारत, आदि

The following are the witness to man's every action - the Sun, the Moon, air, fire, sky, earth, water, heart, Lord of Death, times (morning, night, dawn and dusk), the Lord of Dharma. One must never assume that he can get away with wrong doings just because there is nobody around.
