To find our dichotomy we need go deep in our body, understanding chemicals processes behind our emotions and we need also figure out how the two entity are working inside us with different urges sometimes on conflict.
More the dichotomy is spotted, more clear will be the path to mend it, putting in communication body and brain.
First rule, there are no rules, just seat, stretch your body and breathe;
Harken your breath.
Learn fom him.
Stretching is alphabet to read your body, breath is the native language to understand him.
Daily practice will give to both parts of dichotomy chance to open a conversation;
Month by month, year by year, trust will grow and will fire up the suture to turn our ego into mindfulness.
Means union, prodrome of union is dichotomy.
