In Jainism, Vighai / Vigai means vikṛti — foods or items that are considered stimulating, indulgent, or disturbing to restraint.

In practice, it often refers to things like:

• milk
• curd
• ghee
• oil
• jaggery
• sugar
• honey

Vighai-tyag means giving up these items as a vow of self-discipline and ahimsa.

If you want, I can also explain the five vigai in simple Jain terms.
