One doesn't stay in a state of nirvana by hiding from difficulties. You stay in nirvana by lavishing nirvana on everyone you meet, by giving it away as fast as you receive it.
At each moment we are expressing what we know ourselves to be. If we know ourselves very little we will express and manifest that unconsciousness of our true nature.
If we know who and what we are very thoroughly, we will express and manifest that in what we do.
It is all very simple.
Self-inquiry is a spiritually induced form of wintertime. It's not about looking for a right answer so much as stripping away and letting you see what is not necessary, what you can do without, what you are without your leaves.
