We are in the final stages of egoic madness. Almost the whole world is fighting each other.
The moment you realize you are not present, you are present.
You cannot be both unhappy, and fully present in the Now.
When great loss happens - deaths close to you or your own approaching death - this is an opportunity for stepping completely out of identification with form and realizing the essence of who you are, or that the essence of anyone who is suffering or dying is beyond death.
Complaining is one of the ego's favorite strategies for strengthening itself.
By watching the mechanics of the mind, you step out of its resistance patterns, and you can then allow the present moment to be.
