I want to take a coin and concentrate on it with direct force, put all my attention without having any interrupting thoughts. for full 10 minutes or more.

NOT in this way:
if some thoughts appear let them pass and do not pay attention to it.

No, i want other thoughts DO NOT APPEAR, not that i have to let them fly away, no, i want them to not exist, to have only attention on this coin for 10 minutes and nothing else at all, no other single thought.


how to do it ? currently i can only 1 minute 30 second and later my brain attack me with some random thoughts.
