Intensity
In our culture we have a special case of materialism (the belief that more is better). This is the belief that more intense is always better. Intensity naturally draws the attention of the person. The brain is drawn preemptively to intensity, because in nature, intensity is rare and important. Modern culture though has used technology to present ever increasing intensity as a consumer product.
Intensity, however, usually increases sympathetic shift without increasing pleasure, wisdom, or self-possession. The ego is also seduced by intensity, wrongly inferring that the intense is greater or higher than what has come before.
Deadened bodies often look toward intense experience to feel alive. But intensity 'abuse' usually causes a further down-regulation, increasing the deadening in the body. Furthermore intensity draws one 'up,' and grounding is lost.
