"Study the book about aggregates (khandhas) carefully. Memorize it, and then try eating while observing. Compare what you find with what's in the book about aggregates and what you think you perceive.
So, you take rice, pick up curry, eat the lime salad. When eating lime salad, do you find the lime or do you find sourness?
When eating peanut paste, do you find peanuts or do you find the creamy taste? When eating fried fish, do you find the fish or do you find the taste? Shouldn't we accept what we actually find? Isn't this worth examining? Study - there are only creamy taste, sour taste, bitter taste, spicy taste, salty taste. Isn't this worth investigating? This is the truth.
When you know the truth like this, will craving (samudaya) still arise towards it? No, it won't, understand? Think about it. Regarding the rūpa (material form) of the creamy taste, isn't the desire and attachment to eat it as 'fried fish' taught as craving, the Truth of the Origin of Suffering? If there is craving, the Truth of the Origin of Suffering, won't new aggregates arise?
Can these aggregates escape aging, sickness, and death? What truth is this? (It is the Truth of Suffering, Venerable Sir). This happens due to wrong attention. The arising and passing away of the rūpa of taste is the Truth of Suffering. Understanding the Truth of Suffering is Right View, the Truth of the Path. When the Truth of Origin dies, no new aggregates arise - that's the Truth of Cessation.
Isn't this taught as Path and Cessation? One can end the defilements even while eating. Isn't this worth studying? When observing like this - when seeing, hearing, smelling, tasting, touching, thinking - check if greed arises in me. Isn't this worth examining? If greed arises, it means I haven't yet found the true nature of things.
Even if you can explain it correctly, have you really understood? If so, do you still need to ask others? Test with visible objects, sounds, smells, tastes, touches, and mental objects. If you can contact them without love or hate arising, then it's correct. When you see impermanence, you're certain. Strive to reach this stage..."
