I find your question interesting. What is a true vision? Does anybody know what a true vision is?
We have the freedom as I see it to interpret the world in different ways, and we can be aware of how a thought makes a such a difference to what is percieved.
As for myself, it is important to not decieve myself, being blind to what is difficult and painful. Trying to be open to what is.
These are just some thoughts that came up in relation to your question. And how nice it is to get high on your own juices.
