It is a reasonable act to reject whatever hinders the attainment of one's ideal. The rejection of personal possessions, of physical goods and worldly powers which become such hindrances, is therefore not wrong. But we ought to distinguish between the mere external symbol of possession and the real internal attachment to it. The latter is solely mental. True asceticism must be practised inside the heart. A publicly advertised asceticism has no intrinsic value.
