I recommend the book – The Wisdom of Insecurity by Alan Watts

When we experience anxiety, we are almost always trying to fix, fixate, the present – in other words we want to stop life, stop change, stop flow and control it. We want security

We want security but security is fixed and life is flow (life cannot be fixed) so the more security we desire the more insecure we become. The only way to over come insecurity is to embrace insecurity.

“To put is still more plainly: the desire for security and the feeling of insecurity are the same thing. To hold your breath is to lose your breath. A society based on the quest for security is nothing but a breath-retention contest in which everyone is as taut as a drum and as purple as a beet.” ― Alan W. Watts

“But you cannot understand life and its mysteries as long as you try to grasp it. Indeed, you cannot grasp it, just as you cannot walk off with a river in a bucket. If you try to capture running water in a bucket, it is clear that you do not understand it and that you will always be disappointed, for in the bucket the water does not run. To “have” running water you must let go of it and let it run.”  ― Alan W. Watts
