A dog that barks at every person and every leaf that moves is worthless as a watchdog. A car alarm that goes off because the wind blows, or someone walks by, is worse than useless – your neighbors will be glad someone steals your damn car, just to get that horrible noise out of their lives for a few days. And if we are tense and suspicious all the time, this is not good armor and not good radar. No military can be on high alert all the time – things break down.
Meditation is adaptive – this means that the power driving meditation and making it work is your body's innate intelligence, which is only interested in helping you to survive and thrive. This is the natural tendency of meditation, by the way – you can observe this in yourself, and you can find it out through interviewing others. Instinctive Meditation is just a name I give to a system for recognizing and utilizing what happens naturally during successful and healthy meditation. I developed it by listening to people who were thriving in meditation and in life, and I learned in a different way by listening to people who were taking damage.
As part of this adaptive process, one of the dynamics that goes on during meditation is that your body and mind will re-calibrate your danger signaling system, to make it more accurate. You'll find yourself going deeply into relaxation, and then your nerves will jump a bit as they replay the memory of a threat that you perceived. Then your nervous system will study the relationship of that perceived threat with your current sensory intelligence about your world, and evaluate the best course of action. This is an almost involuntary process. It has great survival but everyone almost without exception hates it because they think it shouldn't be part of meditation. It feels like you are at home having dinner, or resting, and a technician from the alarm company comes over unannounced and starts testing the alarm system, opening and closing doors and windows and checking the perimeter. If you allow this process, you will find that after meditation, your danger signaling system is more accurate with fewer false alarms, and you can go through life more relaxed because you trust your sensors.
