nārcitāḥ salilair api
yadi niryānti te nūnaṁ
In a field there may be holes made by snakes and mice, but when there are very big holes, it may be supposed that jackals live there. Certainly no one goes to take shelter in such homes. Thus the homes of human beings where atithis, uninvited guests, are not properly received are like the homes of jackals.
