As one dwelling on earth perceives objects in their reversed relations at the time of one's death SO you do not perceive what is for your good or profit. Those moribund do not relish what would do them good.
न नूनं चात्मनः श्रेयः पथ्यं वा समवेक्षसे॥ मृत्युकाले यथा मर्यो विपरितानि सेवते। मुमूर्तृणां तु सर्वेषां यत् पथ्यं तन्न रोचते॥
