Thoughts manifest within my mind via my brain, which is basically a network of neurons all interconnected like a dense sponge with multiple levels and layers.
The thoughts I think more often create stronger connections between the neurons (neuron arms touching other neurons,) like bridges or pathways
making the charge that stimulates them (and allows me to be aware of the thought) also stronger,
so that those thoughts become easier to locate within the whole network, in the same way a well walked path is easier to sprint through than a dense, unexplored jungle.
The more I think a thought,
the easier that thought becomes to think.
The more I feel a feeling,
the easier that feeling
becomes to feel.
I know this works physiologically because:
my brain and body produce 'receptor cells' like outlets that the emotional chemicals (neurotransmitters that my brain produces) can 'plug' into in order for me to 'feel' the emotion.
As my brain and body replenish these receptors, the emotional chemicals more frequently produced likewise tell my body to produce more of those receptors that they can plug into and thus:
I can feel a 'craving' or 'longing' for an emotion.
I can feel 'comfortable' in an emotion I don't actually like.
This is also why I can have mixed feelings, and why some feelings can 'feel' stronger than others.
The more I feel a feeling,
the easier that feeling becomes to feel.
The more I do an action,
the easier that action
becomes to do.
I know this works physiologically because:
My brain and body work together to create what is called 'muscle memory' when I repeat a motion.
('muscle memory' is basically the neuro-network in my brain [my frontal lobe's pre-motor cortex & motor cortex, and my cerebellum], AND the creating of more muscle cell nuclei [myonuclei] within each muscle cell, which is what allows me [my neuro-network] more efficient control of the cell),
so that even after I stop riding a bike for years, as example, I can return to that motion without having to re-teach my brain and muscle cells to coordinate for these movements.
The more I do an action,
the easier that action becomes to do
" The more I ..." "the easier that ..."
is not an arbitrary coincidence,
it is an evolutionary tool!
I recognize that despite our different cultures and nations,
we've socially accepted this truth when it comes to things like:
