Even when your vision is clear without blurs

You could be just looking

Or you could be seeing and becoming aware

Or you could be watching and noticing what is happening

And when you reach a stage of noticing

Are you able to understand clearly what is really going on?

There could be mental blurs in your mind.

For this you need to think positively 

engage in constructive activities

move the mind from outer distractions to your inner self

practice this by focusing on a dot
