11.23.22

labdhvā janmāmara-prārthyaṃ mānuṣyaṃ tad dvijāgryatām /
tad anādṛtya ye svārthaṃ ghnanti yānty aśubhāṃ gatim //

22. Having fallen upon human life sought after even by the celestitals, and even there in the foremost life of a brahmin, those who neglect it and spoil their own purpose, surely reach the (most) miserable goal.
