कोऽन्धः? को बधिरो? को मूकः?

Sri Adi Shankaracharya  -

कोऽन्धः? – योऽकार्यरतः

को बधिरो? – यो हितानि न शृणोति ।

को मूकः? -  यः काले प्रियाणि वक्तुं न जानाति ॥

Who is blind? He who keeps engaging in wrong acts.

Who is deaf? He who does not listen to right advice.

Who is mute? He who does not know how to speak sweetly when the time arises.

The Jagadguru said that one must never be deaf to the instructions of the Guru. Even if people engage in various activities for the purpose of filling their stomachs, they must never swerve from Dharma.
