Meditation is a practice often performed in three steps: find a still body, still breathing and still mind. There exist a lot of different variations with a lot of different goals. I would like to introduce a personal and general framework that describes my practice. This simple idea is schemed on the following figure.
Causality: As a scientist, causality is of utmost importance for me. The idea really started to grow with Copernic, Galileo and Kepler ( five hundreds years ago). Simply put it's: 1/ No dogma; 2/ You should be able to repeat the experiment; 3/ You should explain (or quantify) it using laws (most of the time: mathematics). We notably sent a man on the moon and fueled the industrial revolution using this. In physics it means that an event A is going to cause an event B threw an exchange of force or energy (apple falling because of the earth's attraction). In psychology it means that a reaction is going to be caused by an event threw an exchange of information (I am happy because I see a kid laughing.)

Absolute, unmanifested field: If you are familiar with meditation it is Sahasrara; if you are familiar with Jung's analytical psychology, he called it absolute knowledge. It can bee seen as the source of manifestation and where liberating currents flow.

Spacetime continuum: Thanks to Science, we now know that it is observer dependent. Two consequences are: it is possible to fit a one meter stick in a ten centimeters card box (space); two events can happen at the same time for one observer and with a delay for an other (time). We manifest from the absolute field to the spacetime continuum and liberate in the opposite direction.

Synchronicity. Originally introduced by Jung in the 50s as a meaningful, acausal, spatio-temporally transcendental connection between inner and outer realms. Inspired by Mansfield, I have updated the concept considering Buddhism rather than Taoism for the philosophy; some newer quantum mechanics for the science; and kept Jung analytical psychology.
