23. Wise people would do well always to read this account of Indra and listen to it at every Parwan (new moon or full moon), as it is calculated to enliven the functions of the senses, to secure blessings and glory, to remove all sin, to bestow victory over one's enemies, to conduce to auspiciousness and to confer longer life.
