For thousands of years, lots of people from all cultures & traditions have meditated successfully -- with relaxed grace, beautifully silent inside, brilliantly wide awake, feeling fascinated & exclusively focused in the Eternal Infinite Now -- after consuming every food & drink on the planet.
The same quality of personal meditation experience has been had frequently, all over the world, for thousands of years, while their bodies are in any & all positions & even during every degree of sickness & health. They can be any person of any age, with or without meditation training & often they don't even identify themselves as meditators.
Those kindhearted illuminaries successfully meditate in classic positions, while standing, walking, doing dishes, laying in bed, while physically watching an "external" event -- literally anywhere & everywhere. And also while sick laying in bed in every position @ home & in hospitals, while in nursing homes, while inside medical equipment like MRIs, during all types of medical scans, with breathing tubes down their nose & mouth & while in hospice.
They also meditate successfully while taking nearly all types of medications, recreational drugs, even those that severely alter consciousness.
They look at everything as golden opportunities to find new experiences, techniques & new ways to explore their Inner Universe.
The fastest & easiest way that I've found to get There -- supremely relaxed, quite inside & brilliantly wide awake in the Eternal Moment of Now -- is to personally fall into true love with the actual wide-awake eye-witness meditation experience & the Silence of the Inner Universe, which is @ the center of all our spiritual beings.
Once you do that & identify with that Silence & deep serenity as WHO YOU REALLY ARE, then getting to that high meditative state of being ... can happen anywhere & everywhere in less than the twinkle of an eye
