Good vs bad, heaven vs earth, inside vs outside, right vs wrong...
It is because the two faces of our mind that make us suffer. People who suffered from mental depression is also due to their entangled mind between two sides: happy vs sad or right vs wrong.
The core meditation technique taught by Great Perfection masters is to 'see but don't judge'. Once a judgement is made, then a person tends to stand on sides and this is the beginning of 'samsara' (sorrow).
So, understand the core concept of Great Perfection, we also understand that the law of karma does not apply to a Great Perfection teaching as 'good and bad' are only relatively speaking.
A good thing to a person may be an unforgivable act to another. So, how can we judge and say which is good or bad? Which side would receive bad karma then?
Hence, the teaching of Great Perfection is thought as a dissident of Tibetan Buddhism and this teaching naturally invites controversy.
Staying on this context, there are many games in the West that could make players crazy. For example: The Three Kings, The Closet Game, One Man Hide And Seek, Dry Bones, Bloody Mary etc.
Of course believers say that the Devil was at work. But a Great Perfection practitioner would point out that it is not the Devil but the games made the player's mind to be in a constant state of 'yes or no' self-talk state. So long as the person failed to snap out of this yes-no between stage, he/she would become paranoid or crazy.
The Great Perfection's remedy for this case is just to stop thinking and 'see' so as to get the 'what-you-see-is-what-you-get' feel. Once a person can grasp hold of a secure feeling, then he/she will come back to his/her senses that there is nothing to bother him/her. In Great Perfection, when a person walks out of his/her state of fear, he/she is said to be 'self-liberated'.
Of course, not all players who played the above spirit conjuration games would face with problems. If you still remember the 'doer' and the 'thinker' that I have brought up in earlier postings, then you would have guessed that only a 'thinker' will get into trouble but not a 'doer'.
This is because a 'thinker' would engage in an endless state of ding-dong as to if the ghost would come or not. After a few hours of 'yes-no' self-talk, a thinker will go crazy. On the other hand, a 'doer' just do and less thinking. So a doer will feel the game is stupid.
In short, there is nothing so 'great' about 'Great Perfection'.
To sum up: Great Perfection says that our mind is constantly switching state: happy-calm-sad. The '-' represents the intermediate states. If we are aware that the 'happy-me', 'calm-me' and 'sad-me' are all myself; then we have master the gist of Great Perfection.
So said, if you still thinking of becoming a 'Buddha', then a Great Perfection master would wallop you with a baton!
