Pain, crisis, illness, loss, death are all natural facts of life. You did not cause them nor were they caused by others. They are an inevitable part of natural life in this world. Of course, they can be very cruel. But the greatest cruelty is blaming yourself or other human beings for something that depends neither on you nor on them.
Blaming yourself and others for what causes pain in this world is the greatest form of cowardice, because it underlies the malicious fear of holding the Creator or Mother Earth responsible, only to preserve the lure of their goodness.
