It is not ours to create a safe space for others, in fact quite an injustice to so. For both them and you.
The pursuit to extinguish suffering has caused more than any other endeavor
The only thing that you can do with out consequences of more harm than good is:
1). Avoid creating misery. There’s plenty already in existence to go around without making more, for you or others.
2). Share the discomfort of others. While no one can carry another’s burden; being present for them invigorates strength so they can.
