One aspect of eating is tasting. At what point do we really taste our food? I would like you to experiment and discover for yourself at what point you really start tasting the food. Another is swallowing our food, to consciously swallow our food.
Another thing that happens when we eat our food is we like certain food and dislike other food, or we neither like nor dislike the food. But most of these reactions happen habitually. So at least to be aware, to be conscious of this as a strong habit.
Another thing about food is the quantity of food. The Buddha advised meditators to avoid two extremes. One extreme is eating too much; the other extreme is eating too little. So again following the middle way in relation to eating. So while eating, how can we discover this right quantity?
We have to listen to our body when we are eating. So if we can listen to our body or the sensations in our body, then we’ll be able on our own to discover the right quantity of food. It is very helpful to develop a sensitive body.
