Whenever someone talks enthusiastically about meditation, I remind myself that all the popular meditation gurus I see on Youtube talk nonsense, pseudoscience, lack common sense and use manipulative psychological tricks. None of them admit any errors and ironically are quite conceited for those who claim to have conquered ego.
I am sure meditative states must feel nice. But all I see beyond that are cults and none of the meditators seem that much at detached peace. They get incensed at criticism.
