@Sarana A further question for you…
You appear to think monks who wrote entries to the canon, were of impeccable character. You seem to have little familiarity with the canon. In Buddha’s day there were monks as noisy as fishermen, Chatuma sutta. There were times when Buddha withdrew from the society of monks, and preferred to live with wild animals. (a wild elephant, and a monkey who reportedly attended on him). Quarrels of Kosambi monks!
Monks rebelled when they were asked to cut down on the number of meals, Baddali sutta.
Monks like this surely appeared on a later day after the passing away of Buddha, rebelling against the teaching, poured their upanasadic ideas into the canon?
MN 19 and MN 4 describe the Four Buddhist Jhanas, Buddha’s awakening, with great clarity. There is no reference to Arupas at all.
Sandha sutta repeats that only the naive meditator (donkey meditator) resorts to Arupa meditation, a practice prevalent among non-buddhist practitioners.
Buddha to be, had practiced Arupas under some Indian ascetics, only to find that Arupas do not lead to deliverance from suffering. MN 38. Thus he rejected these practices.
Yet 25000 years after the incident some Buddhists (layman and monks) are stuck on Arupas, which reflects the craftiness of some remakably clever Upanisad oriented buddhist sutta makers (liars?), that forced their beliefs through the back door. Wily Hindus covered all their bases. Only the buddhist with with little dust could see. Others got carried away by lies.
As for MN 111, we can start another thread saying … “Why is Buddha calling Sariputta a donkey?” based on the teaching on Sandha Sutta. That would be some serious fun. Do you get my drift dear @sarana?
When you come to the home of a well conducted monk and accuse him of treachery be careful of what you are saying?
Are you familiar with Kokalika sutta?
An excerpt from Kokalika sutta, of Sn.
Once when the Buddha was staying in the Jetavana Monastery at Savatthi, a monk called Kokalika came up to him and said:
“Sir Sariputta and Moggallana are full of unwholesome desires. They have been quite taken over by unwholesome desires”
The Buddha answered:
“Kokalika, don’t say such a thing! Have confidence in your mind as far as they are concerned; They are well behaved”
But Kokalika repeated his accusation against the two disciples.
The Buddha replied as before, but the monk again insulted the disciples the same way…"
The comment is getting too long. You can read the rest of the sutta later.
