What is the importance of perception?

How? Why?

@Winterwanderer: Perception, how we see things, affects our mentality, how we think.

No?

Well the way you just said it is different than the original phrase. The phrase "Perception is Reality" equates perception to reality, which is not a true relation, but in the way you said it, also no our perception does not necessarily define or even affect the way we think, though it has the capacity to (& often does for the general public), it only affects us when we give it the power to.

@Winterwanderer: Aww. Tomatoe .... Thank you for info. All the best.

Tomatoe?
