Here be a special trick to see the other side:

In the light, sit between two large mirrors. Close one's eyes. Breath deep and regularly. Think about absolutely nothing save exhaling alone. Become, as it were the breath you are exhaling. Feel only the absolute release they call 'zen'. When one has lost all sense of self and knows only the release of breath, open one's eyes into the mirrors in front and behind you. 

Absolutely do not in any way change one's actions, goals, or mannerisms. All in existence that matters then is the reprieve of release through exhaling. When, at some point, you begin to see things in the mirror, think nothing of them; no excitement, no fear; breathe and breathe alone until you desire cessation...

Alternatively, sit before a black mirror in a pitch-black room with a lit candle behind you. Do the same as stated before...

A wee secret of Magic for you.
