The Simplest Way
The simplest way to Enlightenment/God Realization is to see everything as Buddha Mind/God. Every phenomena is the manifestation of God/Buddha Mind.
Whatever we see as "not God" is exactly where we are stuck. Whenever I resist an experience, there is suffering. When I fully experience it, it reveals itself as bliss.
It is very simple, but not easy. When awareness is exclusively identified with the small self, it naturally functions dualistically - which creates a filter preventing us to directly experience Existence. When awareness awakens to its own nature - and (often later) to Big Mind - it is free to function in a more transdual way. There is no separation and a perception of the radience of all phenomena. And this more transdual view is brought into more and more areas of life, until everything is revealed as God - in all situations.
This gives us a good guideline for long-term and everyday practices.
