The headmaster knows that he is only the caretaker, not the owner. He is not attached to these articles; he knows that they belong to the government.

You have to give up your pursuit of sensory objects if you seek lasting peace and joy. Material wealth brings along with it not only joy but grief as well. Accumulation of riches and multiplication of wants only lead to alternation between joy and grief. Attachment is the root of both joy and grief; detachment is the saviour. Attachment (ashakti) is death (maraka). Non-attachment (anashakti) is liberating (taraka). A millionaire pays income tax with tears in his eyes, while a headmaster joyfully gives up the furniture and laboratory appliances of his school when he is transferred to some other place. Why? The headmaster knows that he is only the caretaker, not the owner. He is not attached to these articles; he knows that they belong to the government. So, too, feel that your family, house, property, car, etc. are all the Lord's property and you are just a trustee; be unattached and be ready to give them up without any murmur, at a moment's notice!
