As the question is specifically about me, a disclaimer becomes inevitable :
My food habits are more or less the same for 365 days (which includes the days of daslakshan/ paryushan). You may message me personally on the forum’s inbox to know more about it.
Nothing much changes for me in terms of food habits. What I mean by celebration is spending more time for doing Pujan / Vidhan, reading scriptures, and introspection. And this, I certainly did for all 18 days. In fact, it is something which ought to be done 365 days a year. But since we can’t do so, we have these parv during which we try to do it for some days.
And with all due respect to the intention with which you raised this question, I would like to share one thing -
Food habits need not and should not be identifed with what Jainism is. I agree that it has its place. But Jainism, as a philosophy, a religion and a way of life, has plenty much more to say rather than what to eat and what not. Any discussion pertaining to Jainism should neither begin with it, nor should it end there. No religion or philosophy does so. Think about it.
