Text 3.71.23

शोकार्तानामनाथानामेवं विपरिधावताम्।
कारुण्यं सदृशं कर्तुमुपकारे च वर्तताम्॥

śokārtānām anāthānām evaṁ viparidhāvatām
kāruṇyaṁ sadṛśaṁ kartum upakāre ca vartatām

śoka-ārtānām = to persons who are afflicted by distress; anāthānām = helplessly; evam = in this manner; viparidhāvatām = running around here and there; kāruṇyam = merciful; sadṛśam = it is appropriate; kartum = to be; upakāre ca vartatām = while helping others.

It is appropriate to be merciful to persons who are afflicted by distress, helplessly running around here and there in this manner while helping others.
