Thank you for the clarification of vicikicca, and especially the added explanation of khanka vicikicca.
I did some searching and found this:
Mahanama Sutta

I wonder if this is related to what you said about Mahanama.
For the case of Mahanama, his angry instances were then patigha and not vayapada, but he on his own could not tell the difference?
I did not find anything about the story of Ven. Moggallana getting “lost”, and here I do have some doubt, I must admit. Wherever Ven. Moggallana “went”, it would have been in one of the 31 realms, would it not? Someone of his caliber certainly would not have been lost in one of those realms. Just a thought.
Thank you,
Lang
