There are two ways, one difficult, the other easier but takes a bit of time.

1. Difficult: practice until your meditation skills are good enough to get into a state of Pure Consciousness (please look it up) for long enough to enter the temples of the mind and just see and hear. Be a receptacle to stimuli without thinking about them. God will eventually appear - but don't accept everything at face value. Ponder your visions / auditions outside that state.

3. Easier: Buy a mirror and look long and deep until you realise god.
