Think before you act

दृष्टिपूतं न्यसेत्पादम्
वस्त्रपूतं जलं पिबेत्‌ ।
शास्त्रपूतं वदेद्वाक्यम्
मनः पूतं समाचरेत्‌ ॥

One should place the foot only after carefully watching.
One should drink water only after passing it through a filtering cloth.
One should speak only those words that agree with scientific scriptures.
One should act only after careful deliberation.

Look before you leap.
Think before you act.
Vision without action is a daydream.
Action without vision is a nightmare.
