An interesting topic, Noah. I have been studying this in myself over the past few months, specifically during my menstrual cycle. Having observed both myself and my partner at this time of the month, I have noticed the same tendencies you have spoke of- I lose touch with my obersvant self, instead getting swept into an emotional tidalwave. My partner does the complete opposite, also losing the seat of the observer, to a standpoint completely removed from all emotion and sensation. I think, at this time of the month, my Shakti becomes accentuated, as does my partner’s more masculine energy. Where do the two meet? This is our challenge. Finding balance.
Balance, however, can only be found if one allows for the ebb and flow of the energies, in the same way one sways in Vrksasana/Tree. So to answer your question, how could one bring about further balance in our yoga practice? Personally, I like to allow my mind to delve fully into both polarities, being mindful of which it is most naturally drawn to. I may, at the beginning of my asana practice, be very experiential and fully tuned into the sensations in my body, and use this as a vehicle to pull back, and view the experience third-person. I think it is a constant dance between the two- we can only find our equilibrium if we recognize what each spectrum feels like. Allow the mind to explore every standpoint, and it will come to rest in the core of our being.
