Practise Ahimsa and Brahmacharya in thought, word and deed. Practise Saucha and Arjava (straight forwardness). Try to keep up balanced mind. Be cheerful always. Keep up Shuddha Bhava. Try these three kinds of Tapas (physical, verbal and mental) and control your actions.
Be careful in your speeches. Speak little. Speak sweet loving words. Never utter any word of harshness that can affect the feelings of others. Try to speak the truth. Thus put a check on the Vak Indriya and the impulses of speech.
