First of all, thank you for your metta. I felt samadhi just by reading the text.
Sādhu Sādhu Sādhu _()_
<br />
Secondly, thank you for explaining it in an easy-to-understand way.
Analogy of root problem(disease) and symptom is worth.
In my understanding, we maintain disease(samsara) for an infinite amount of time, because we love the effects of painkillers(amisa sukha) so much.
We cannot imagine what is real recovery(nibbana). Only the Buddha can find it.
I want to contemplate this metaphor a little more.
Once again, thank you for your help.
May the blessings of the Buddha, Dhamma, and Sangha be with all beings.
