"Don't we have the six sense doors - eye, ear, nose, tongue, body, and mind? When they exist, isn't it worth contemplating what the Buddha taught?
'Cakkhuviññāṇaṃ aniccaṃ, sotaviññāṇaṃ aniccaṃ, ghānaviññāṇaṃ aniccaṃ, jivhāviññāṇaṃ aniccaṃ, kāyaviññāṇaṃ aniccaṃ, manoviññāṇaṃ aniccaṃ.'
Didn't the Buddha teach that after seeing, it ceases; after hearing, it ceases; after smelling, it ceases; after tasting, it ceases; after touching, it ceases; after knowing, it ceases? Shouldn't we examine this carefully?
These are #the_first_teachings one must understand. Isn't this worth contemplating? Very precisely. Isn't this worth examining?
Didn't Bāhiya and Mālukyaputta complete their duties as monks just by understanding 'in the seen, just the seen; in the heard, just the heard'? Haven't we heard about stopping at seeing, stopping at hearing? Even while on alms rounds.
Shouldn't we examine what exactly we're seeing when we 'stop at seeing, stop at hearing'?
Are we seeing people, or are we seeing the five aggregates? #In_these_aggregates,_is_there_anything_to_love_or_hate? There's nothing to hate. There's nothing to love. Isn't this worth contemplating
