The brahmanas or vaisnavas do not live at other cost.
Since brahmanas and Vaisnavas are direct servants of the Supreme Personality of Godhead, they do not depend on others. In actuality, everything in the world belongs to the brahmanas, and out of their humility the brahmanas accept charity from the ksatriyas, or kings, and the vaisyas, or merchants. Everything belongs to the brahmanas, but the ksatriya government and the mercantile people keep everything in custody, like bankers, and whenever the brahmanas need money, the ksatriyas and vaisyas should supply it. It is like a savings account with money which the depositor can draw out at his will. The brahmanas, being engaged in the service of the Lord, have very little time to handle the finances of the world, and therefore the riches are kept by the ksatriyas, or the kings, who are to produce money upon the brahmanas’ demand. Actually the brahmanas or Vaisnavas do not live at others’ cost; they live by spending their own money, although it appears that they are collecting this money from others. Ksatriyas and vaisyas have no right to give charity, for whatever they possess belongs to the brahmanas. Therefore charity should be given by the ksatriyas and vaisyas under the instructions of the brahmanas. Unfortunately at the present moment there is a scarcity of brahmanas, and since the so-called ksatriyas and vaisyas do not carry out the orders of the brahmanas, the world is in a chaotic condition.
