How can you know the other?
You can love, and through love this miracle happens.
If you love the other, great understanding arises on its own.
Not that you try to understand the other:
You simply love the other as he or she is, with no judgement.
"Do not accept anything simply because it has been said by your teacher,
or because it has been written in your sacred book,
or because it has been believed by many,
or because it has been handed down by your ancestors.
Accept and live only according to what will enable you to see truth face to face."
