Awakened fierceness and wrathfulness are not the same as the human emotions of anger or revenge etc, they are just, and just the response to a condition.
I am thinking of the recent earthquake in Japan - as having combined wrathful qualities of Vajra, Ratna, Padma and Karma Dakinis or water, earth, fire and wind. The earthquake is not tainted with any kind of maliciousness, it is a result of the earth moving, shifting doing what it needs to do in order to maintain or foster balance, equinimity, harmony. Destruction and creation both result from it. It has no preference its JUST doing its job.
Have a look here at this animation for earthquakes around the world since only1980. Reminding me of how our sublte bodies change and shift when our bodies move. Are we not a microcosm of the Earth?
and this image from 1900-2017 looks to me like a windhorse galloping
I hope that one day my fierce and wrathful qualties are JUST so - reponding with full awareness for the benefit and bliss of all beings. Until that time I will try to concerntrate fiercely on bodhichitta for myself and others as the prerequisite for the wisdom awareness to unfold.
And as hapenstance would have it this image that I created for Karma Dakini for Khandro La's book ( Dakini in the Cotemporary World) and was not published (and was thinking about for this post) showed up on my phone as a memory for today ! ha ha hee hee
