હંસ બગલા એક રંગ, ચલે સમુદ્રકું સાથ;

haṁsa bagalā ēka raṁga, calē samudrakuṁ sātha;

Literally: The swan and the heron are of the same color, and they walk to the ocean together.
What it means: People may look identical on the outside and walk the same path, but their inner nature and desires remain completely different.
