A bhikku at my local Therevada center was saying last week that he had a lot of fun giving a talk on the dhamma at a conference recently. At first, he was worried about whether it would be profound enough to be published. Then someone told him that it does not matter whether he is published, he is giving the gift of the dhamma. Then he said he felt free, and was having a lot of fun giving this talk about something which is near and dear to him, without worries about whether it would result in anything. Just the act of giving the gift of dhamma, was fun for him. I can understand how that would be pure enjoyment. It's a joy to talk about the dhamma, with people who might understand. In the day to day life that I experience, everything is contrary to the dhamma. Most people want to talk about gaining or being something, or of discontentment about life or politics or weather, things like that. So, it is not much fun to speak to people about things contrary to the dhamma . But certainly, just speaking about the dhamma with people that can understand the dhamma, that is very fun. No? If I came across someone in my daily life, who could speak about nama and rupa and what that means, I'd think I already reached Nibanna.
