someone responded to this beautifully on this chat. the idea of emptying your mind is not to force it to think of nothing, but to accept thoughts and whatever that comes to mind, understand it and let it pass. have a focus point, the easiest is breathing and keep going back there, and after a while you while feel a sense of calmness. Sometimes it takes you 15 mins, sometimes 45 mins, there's no telling unless if you are a pro with inner stillness. i'm a rookie.

But is it thoughts in your mind, anxiousness, or you have a song stuck in your head - cause the latter can be funny, esp if you are singing out loud in a crowded area lol
