Answer
In interacting with others, one should follow Vaishnava etiquette, which is the standard of proper behavior prescribed in the scriptures.
The essential principle is to see everyone as a spirit soul. Another important understanding is that the Supreme Lord, Lord Vishnu, resides as Paramatma in the heart of every living being. Therefore, an ideal devotee respects every living entity, seeing the body itself as a temple of the Lord.
By cultivating this vision, one learns to respect others properly in daily interactions. This attitude helps one forgive mistakes, avoid fault-finding, and refrain from unnecessary quarrel or criticism.
In this way, one can live a balanced and spiritually conscious life and gradually progress toward perfection and liberation, ultimately going back to Godhead.
Even when dealing with parents or others who may be stubborn or influenced by misunderstanding, a devotee tries to maintain respect and patience, understanding their position and responding appropriately without losing spiritual balance.
