can anyone tell where it is ,might be a atupid fquestions but english is not my first language ,

With your left finger lightly scratch or rub a circular area clockwise
on top of your thumb also for the brushing and sponging actions am i supposed to do them both .one after the other or they are just different techniques with the same purpose

my last questions is about morning and evening affirmation,how much do you practice them ,for example morning affirmation am i supposed to do it all day and for nighttime affirmation am i supposed to do it until i sleep ???


thanks guys for your help
