A man is known by the company he keeps

महाजनस्य संसर्गः
कस्य नोन्नतिकारकः ।
पद्मपत्रस्थितं तोयम्
धत्ते मुक्ताफलश्रियम् ॥

- पञ्चतन्त्रम्

For whom is the company of great people not beneficial? Even a water droplet when on lotus petal, shines like a pearl.

A man is known by the company he keeps.
Keep good company and you'll be counted one of them.
