“I feel (vedana touch) the ground under my soles (touch) but only for a short time, not more than 3/5 secs thus preventing the formation of ayatana.
I see a “beautiful” building but only for a short time, not more than 3/5 secs, thus preventing the formation of ayatana.”
I am not sure what you mean by above. Are you trying to suppress all sensations?
We should not make things hard. All one needs to do is to be aware of whether greed or hate arise in one’s mind, and to suppress those. It is very simple. The hard thing is to catch it quickly. But with practice, it becomes easier.
An indriya becomes an ayatana only when the sense experience taken in by the indriya (say eyes), make one’s mind form greedy or hateful thoughts. If what is seen makes one greedy or hateful, stop looking at it, and focus attention on something different.
On the other hand, if it makes one’s mind calmer by keeping a Buddha statue in the meditation room, that helps train the mind to use that image as one to focus on. Then, if even one does not have the Buddha Statue when one sees a tempting figure, one can bring the image of the Buddha statue the mind and thus help take the mind away from that tempting figure. That is just an example. Each person need to come up with ways on how to take one’s mind away from greedy or hateful thoughts when they arise.
– Another way is to think about the harmful consequences of focusing on that tempting (or hateful) visual. This is what the Buddha recommended as a general solution.
