Space is the place to be and meditation is often touted as a means of being here. There are a number of disciplines but the fact that they can be called that implies some effort, some cause and effect.
However space has no time so no effect. Raja yoga, the act of controlling the mind can lead to an awareness but is subject to devotion. Devotion has no goal and is pure being. Vegan(ism) that has goals is a brilliant form of raja yoga; it requires constant appraisal of personal action. However trying to change another to such a discipline is to want disciples, an army to change the world. This is just politics, masquerading as a new religion of being better, like ecology and sustainability; a load of hocus pocus.

It's fine for those with a gaol, but develops karma. Devotion has no karma so devoted to your soul is just an acknowledgement of life immortal whereas a devotee of the thought is bound to the karma of the body.
