The hardest thing in Buddhism practice is to develop love for all things, all animated and inanimate beings. Not only things but events too. Maybe the difficulty of doing so is the reason why Zen does not focus much on Love. Zen focus on training the mind off distractions, attachments, addictions, delusions, for suffering to unfold as Love in the form of gratitude by itself.

The funny thing to me is that in the end, I must find gratefulness to the same distractions, attachments, addictions and delusions, to the suffering that I am trying to get rid of. It is hard to me to accept that suffering is generated only by the lack of gratitude. Maybe because I am not grateful (?)
