Hello all ,
While reading SN 56.41 Lokacintāsutta
the following passage : quote :
On one occasion the Blessed One was dwelling at Rajagaha in the Bamboo Grove, the Squirrel Sanctuary. There the Blessed One addressed the bhikkhus thus:
“Bhikkhus, once in the past a certain man set out from Rajagaha and went to the Sumagadha Lotus Pond, thinking: ‘I will reflect about the world.’ He then sat down on the bank of the Sumagadha Lotus Pond reflecting about the world. Then, bhikkhus, the man saw a four-division army entering a lotus stalk on the bank of the pond. Having seen this, he thought: ‘I must be mad! I must be insane! I’ve seen something that doesn’t exist in the world.’ The man returned to the city and informed a great crowd of people: ‘I must be mad, sirs! I must be insane! I’ve seen something that doesn’t exist in the world.’
“They said to him: ‘But how is it, good man, that you are mad? How are you insane? And what have you seen that doesn’t exist in the world?’
“‘Here, sirs, I left Rajagaha and approached the Sumagadha Lotus Pond … as above … I saw a four-division army entering a lotus stalk on the bank of the pond. That’s why I’m mad, that’s why I’m insane, and that’s what I’ve seen that doesn’t exist in the world.’
“‘Surely you’re mad, good man! Surely you’re insane! And what you have seen doesn’t exist in the world.’
“Nevertheless, bhikkhus, what that man saw was actually real, not unreal. Once in the past the devas and the asuras were arrayed for battle. In that battle the devas won and the asuras were defeated. In their defeat, the asuras were frightened and entered the asura city through the lotus stalk, to the bewilderment of the devas.
Interesting isnt it ?
so the entrance to Asura realm are actually in the lotus stalk,or some kind of portal to their realm or they have some kind of ability with sub-dimensional portal creation.
the only one i could recalled are those mentioned abt "certain city "from DN 32:
The monks, nuns, laymen, and laywomen should learn this Āṭānāṭiya protection well and completely memorize it. If anyone who does so is approached while walking, standing, sitting, or lying down by any non-human being with malicious intent—including males, females, boys, girls, chief ministers, councillors, and servants among the spirits, centaurs, goblins, and dragons—that non-human will receive no homage or respect in any village or town. And they will receive no ground or dwelling in my capital of Ālakamandā. Nor will they get to go to the conference of the spirits. In addition, the non-humans would not give or take them in marriage. They’d heap personal abuse on them, drop an empty bowl on their head, and even split their head into seven pieces!
Anyone else has found any reference about " Asura cities" where are those city are ?
or reference in the Tipitaka Pali / commentaries ? please share any of your thought, views.
