I have become aware that there are multiple forms of meditation, with several goals and different - contrasting - effects.
One thing I do, or which sometimes happens-to-me, is something I haven't seen specifically described - perhaps because its effects are modest. It is a state of heightened present-moment, here and now, dynamic receptivity.
The first time I noticed it was when I was at college, walking on a path across a field, when I became aware that a warm wind was blowing between my fingers in a pleasant way, and I began to focus on the sensations that were happening to me - the feelings on my skin, the appearance of the path and the grass nearby, sounds of birds and traffic - and quite suddenly my consciousness snapped-into awareness of the here and now of what was happening to me: a state of Present Receptivity.
It didn't last long, because almost immediately I started 'thinking-about' the sensation, which distanced me from this sensory contact; but it was a valuable experience because I knew myself to be orientated and placed - also it dispelled that angsty worry which tends to grind-away for much of life.
Since then, I have always been able to induce the feeling whenever I remember to do it - which is not very often! But one time is in the morning or evening when I step outside to stand and look at the sky.
For just a moment or two, life is not just sweeping-by - but slows to the point that I become aware of myself, floating in the stream of time.
