The easiest way is through activating each one of your five senses of the physical aspect of you:
If you can do this at the same time, and you are aware of this… you are in the present moment, you can also become aware that you are experiencing this by choice.
Breakthrough – Not because you don’t know something, it means it is hard, it just means you did not know.
From this space, you can also be aware of the other three aspects of you: Mental – thoughts; emotional – feelings, and Spiritual – your connection with your higher self (whatever that means to you), from where you have a choice to be aware that you are aware… YOU ARE THE EXPERIENCER. From this state, there is a choice, however vague, to disconnect and BE PRESENT.
Breakthrough – The more you practice, the sooner it will become a habit.
