Our own thoughts should really match our words and acts.
If not, we generate an internal conflict. Seneca said it as follows (quote):
"I will govern my life and thoughts as if the whole world were to see the one and read the other"
I sometimes feel it is a bit dangerous to share all our feelings and thoughts with the world.
However if we could manage to think and feel in such a way that all can be safely known by the world, we reach a high level of thinking and feeling, perhaps almost sainthood.
Anyhow an interesting quote from Seneca, above, worth to think a bit deeper about and perhaps a worthy aim to guide and direct our thoughts and feelings towards a right direction. To a certain extent we have the capability to choose our thoughts and feelings...
