One of the many beautiful features of the human brain is the diversity and capacity to adapt to a constantly changing environment.
There is a spectrum of awareness, from a fully external orientation and awareness of everything that surrounds us, to an internally focused daydreaming state, where can lose ourselves in imagination.
Practising the skill of consciously moving through this spectrum from an external focus to a daydreaming, internal focus has many benefits:-
It switches off the stress response.
It enhances recovery and repair of tissues (healing).
It boosts the immune system.
It opens up creativity and imagination.
It feels really really good !!!
I have described it here. Practise this skill as often as you like.
