Letting go is not doing nothing or becoming indifferent.
On the contrary, it is a dynamic state, continuing to act without worrying about the result, looking to the future without worrying about it. To let go is to give up controlling everything, to give up proving anything, to accept that the other is the other and that I am who I am and not who I had dreamed of being.
To let go is to stop putting life on trial that doesn't give us what we expected. From the moment when we can let go, when we no longer desire to be happy at all costs (in the form we envisage), we discover that happiness is this ability to keep our hands open rather than letting them cling to what we believe to be essential.
Why are you letting go ?
This is the wish of most people who work on themselves to change and evolve. All awakening work starts there.
By renouncing the patterns that keep us artificially in a state that we know, but which take us away from the knowledge of ourselves, we develop an inner space available for the reception of new experiences.
Letting go so as not to be overwhelmed by parasitic desires and give in to temptations. It is an excellent antidote for not reacting to life's inevitable frustrations and disappointments.
Contrary to what can be perceived externally, letting go does not lead to indifference but allows a gathering of one's inner forces which sharpens the senses, fluidifies exchanges and gives access to our deepest self.
Beware, for those who work on letting go, the neutrality obtained is to be differentiated from an indifference controlled by the mind, letting go is a true absence of will. If letting go is not possible in some cases, it is because there is an associated pattern that it would be useful to dissolve.
