i don’t believe this is necessarily a bad practice when done after you sit with the thought using possibly a technique such as mindfulness meditation and it still doesn’t go away despite your best efforts a better technique to tranquilize the mind would be to pay full attention to the uncomfortable though and mentally say “stop” it can be helpful but it should not be done compulsively if it’s not working it’s really just a way to assert a much more useful and fruitful state of mind upon your own present experience
