ખાય ન ખરચે સાધુ જન, ચોર સકલ લે જાય; જયસે મધુ મક્ષિકા, હાથ મીલા પસતાય.

khāya na kharacē sādhu jana, cōra sakala lē jāya; jayasē madhu makṣikā, hātha mīlā pasatāya.

Literally: The saintly person does not eat or spend, the thief takes it all; like the honey bee, one regrets it when they meet.
What it means: Hoarding wealth without using it only benefits those who steal it.
