Your mind can go ahead and imagine what it wants to imagine, but a true friend will always remain true, in spite of the false messages running through your mind.
The only walls that exist are those you have placed in your mind. And whatever obstacles you conceive, exist only because you have forgotten what you have already achieved.
Divide the constant tide and random noisiness of energetic flow, with conscious recurring moments of empty mind, solitude, gratitude and deep...slow...breathing. Of this, the natural law of self-preservation demands.
