Kia Ora,
To make sure we are all on the same page......................[What's clear in my mind is not necessarily clearly understood by others...]
To "think" about two opposing things "simultaneously"[together at "exactly" the same time] is an impossibility ...
For example try thinking about how well some thing's going to go then at the exact "same time" try thinking about the same thing going badly...You will find there's only room for one set of thoughts to flow at any given time...One can hold a conversation within ones mind with the "for and against " thoughts"...But this is not a "split" thought as such, this is just thinking using two sets of opposing thoughts one "after" the other...
Hence why I saying "No two opposing sets of thoughts can occupy the same space at the same time !"
But the good news is... if you swap/can the negative and replace with/nurture the positive thoughts...You'll reap the benefits...Simple, nothing magical nor mystical about it, just pure logical "THINKING"...
However, at times the most simplest things can be difficult to obtain/understand...And this as a lot to do with the ego getting in the way of personal growth "progress"...
I do hope I've clarified things regarding "thoughts" and occupying mind space...[I know at times what I write is not always clearly understood-so my apologies if this was the case]
Now as usual there's always the possibility I could be wrong...But my personal experience with studying my thoughts does tend to match up with the "thoughts" I've presented to you...
You are all quite welcome to try the simple
thought experiment as mentioned above...But I must warn you that at first it's not easy to become "
aware" of the thought or the fact that "thinking" is actually taking place...
"
THOUGHT ITSELF IS THE THINKER !"
Happy Mindfulness Folks...And may you all find lasting peace within because you an't gonna find it elsewhere !
