By sticking to sin continuously one sinks into the intermediate order of beings. By acting both virtuously and sinfully one comes by the status of humanity. By acting only righteously, one attains to the status of the gods.
निष्कैवल्येन पापेन तिर्यग्योनिमवाप्नुयात्। पुण्यपापेन मानुष्यं पुण्येनैकेन देवताः॥
