Spirit refuses to accept my complaint that I am what I am and
I need what I need.

No! He claims. I only think I am whatever and need whatever,
without thinking deeply.

So, if I thought deeply, if I could, then what would I
think I am and need?

You would not think. You would know that you are spirit
living a physical life, and you would be aware that it
is all an illusion, except for the awareness that you
may have developed from playing the Game of Life,
according to whatever rules your particular society has
designed for you.

If different societies play the Game of Life by different
rules, and we are all becoming, more or less, citizens of
a world community, then how can we possibly interact with
each other?

The Rules of Life of different cultures, societies,
communities, or even neighbourhoods do not necessarily
have to be the same.

That may work in separated traditions but when people
migrate from one set of generally accepted set of rules
to another, then surely they need to adapt or learn to
live within the two cultures, without rejecting their
past.

They are their past, or at least they are a product of
past experiences.

The answer?

Respect for past traditions while adapting, or
creating our own set of rules to live by. Whatever
choice we make, however we choose to live our life,
we do choose and accept, consciously or otherwise,
the consequences, if there are any, and there
always are.
