Your pursuit should be the pursuit of the only knowledge worthwhile; the knowledge of Brahman.
Surrender yourself to the Lord. Dedicate your actions to Him. Listen to stories about Him and keep the company of the devotees of the Lord.
Hate no one because everyone is an image of the Lord.
Share the pain of others.
Be alone with yourselves whenever you can because solitude helps you to think of the Lord.
Do your duties properly. Do not neglect any of them.
Speak sparingly and think more.
