Why we can’t eat green vegetables during paryushan

The context from Jain literature about Paryushan emphasizes fasting and austerity as means to purify the soul, minimize passions, and shed accumulated karma. It prescribes fasting for at least three days, with complete abstinence from food and drink, except for boiled and cooled water during the day. If full fasting is not possible, eating only one meal is considered limited fasting. The focus is on repentance, confession, and spiritual discipline rather than specific food prohibitions.

There is no direct mention in the provided texts about avoiding green vegetables during Paryushan. The rules described relate more to the quantity and purity of food rather than specific types of food. The Kalpasutra excerpt discusses monks partaking of uncontaminated food and water, emphasizing cleanliness and purity but does not single out green vegetables as forbidden.

Therefore, based on the given context, the reason for not eating green vegetables during Paryushan is not addressed. Any such practice, if it exists, may be based on other traditional or regional customs not covered in these sources.
