hello
which approach is right for spot focus method......?

1. i should just stare at the spot and should not care about what my mind is thinking......
i mean even if my mind wanders, i should just keep staring

2. i should stare at the spot but i should keep my mind focused too.....i mean i should try to clear my mind and stare at the same time

i dont know exactly how this method works but if my concentration increases just by staring than why should i bother to clear my mind.......there must be something in the staring thats why it is used......
and one more question
should i ignore vision darkening phenomenon and just continue staring or i should clear my vision by blinking....?
