This is a good practice – keep the eyes open, know that seeing is happening and at the same time know another object. If we just focus on seeing, the mind goes to the eyes and it starts to think about what it is seeing.

Try this and make it a new habit. When you’re aware of your breath with your eyes open, sometimes the mind can be aware of the seeing. Then, the seeing becomes more natural.

With the breath as the main object, the mind can also notice that it is aware of other objects; then, you can know that the mind is working.

I recommend that yogis use a main object but also know the other objects. We ground the awareness on the main object and naturally know other secondary objects.
