મુક્તા મનુષ્ય તનું પાયકે, કરત ન હરિસેં હેત;

muktā manuṣya tanuṁ pāyakē, karata na harisēṁ hēta;

Literally: Having obtained a human body, if one does not love God;
What it means: A person who wastes the rare opportunity of human birth without devotion lives a meaningless, ghost-like existence burdened by sin.
