Thank you for your advise, it is very helpful. I shall bare it in mind and continue forward. i will keep in mind that the thoughts coming in are ok before i return to my breathing.
I shall also, at least for now, forget my hip straining half lotus position!
You have helped a great deal with my troubles, thank you again.
