"There is no this causing a that" therefore it is not your fault.

Guilt is coming from an opinion that somehow the situation could
have been different, which it could not have... "Everything is arising of its own".

Surrender "feeling guilty is wrong" it is also arising of its own.
"Surrender everything as it arises".
 
Judging that the feeling is somehow improper takes us out of the "crest of the wave". All is perfection(God) even events that appear tragic.

This is how I use the teachings when such an event arises.

Love,
