1. You should be trinad api sunicha. If someone abuses you, hurts you, humiliates you, even if you are not wrong, still be quite. This is sadhu. If you are not acting like a sadhu, then what is the benefit of putting dress of a sadhu.
2. Don’t give trouble to any living entities, either physically, mentally or emotionally.
If you get something from someone, you must reciprocate. Otherwise you have to come again and pay. So whatever you get, reciprocate. Don’t take burden.
To have mental concentration one must be cheerful and peaceful. By cultivating friendship with equals, respect for seniors, compassion for juniors and indifference towards sinners one will destroy envy, hatred and aversion and become happy and serene.
Srila Prabhupada stressed 4 rules in japa: early morning chanting, full concentration, distinct pronunciation, attentive hearing.
