A closed mouth catches no flies

उद्यमेन हि सिध्यन्ति
कार्याणि न मनोरथैः ।
न हि सुप्तस्य सिंहस्य
प्रविशन्ति मुखे मृगाः ॥

- पञ्चतन्त्रम्

- हितोपदेशः

Any work gets accomplished only by hard work and not by mere pledges. Animals by themselves, do not enter into a sleeping lion's mouth.

A closed mouth catches no flies.
If wishes were horses, beggars would ride.
Vision without action is a daydream.
Action without vision is a nightmare.
