Brain brain brain, what a marvel you are.
You fire neurons back and forth, share an insurmountable amount of information and data in multiple forms and conditions as well as require a need to consciously rest, recover and recharge while providing vital support to our physical body as we sleep so that we can wake it up and begin it all again.
It helps us learn, retain, consider, assess, decipher, and decide. It helps us to remember, to relate, to assosciate, and to imagine what it is to be our self in this world surrounding us - we see how we compare to all that is around us.
If enough care and attention is taken, we can also chose to face our behaviors, patterns, habits and conditioning. By studying these things, we can learn about our selves and seek out what it is that causes us to subjectively feel whatever it is that causes personL suffering as well as personal joy.
Once we identify our habits that we feel are no longer serving us, or even worse - harming us, we can determine cures or remedies to break such patterns and try new approaches.
Train, train, train
Training is a beautiful idea. The concept of becoming good at something and achieving accomplishment within the field of practice spells "rewarding" all over it, especially if it is something that provides support to more than one of our bodies of self. When I refer to our bodies of self, I am referring to the physical self, emotional self, spiritual self, conscious self, and subconscious self.
For example, if someone takes on a sport I order to become more athletic, more agile, more in shape, more social, and something that provides a M serving to the spirit, it can be identified as a very beneficial and rewarding habit.
This idea can be considered a hobby, a personal practice and a discipline.
