Q+A: What is the simplest and fastest meditation I can do?
Your question is not as simple as you may think. Realize that meditation is a wonderful 2,500 year old practice, but it is 2,500 years old. It was created for a world far simpler than the one you now live in. No matter what style you begin with, you will undoubtedly find you will outgrow it as you advance and begin to search for better, faster, deeper practices; which is as it should be.
Some people practice a lifetime before realizing that every door they open also opens a window as they realize there are ever more doors to explore. When you start with the idea of reducing stress and anxiety you inevitably discover those are surface ripples for the delusions you now take as realities. This is part of the self-realization that anyone who has meditated for any length of time begins to undertand.
If you are serious, begin your journey with a reputable school to learn the basics of breathing, dropping in on your thoughts and letting them go. Those are the three core elements to any style of meditation whether it is Vipassana, Samata, Zazen or some manifestation of them. Just as every school teaches you to not cling to your thoughts, forget about clinging to a single school, as each is woefully out of date for what you are looking for. Recognize the non-attachment they all talk about applies to their own school as well.
I teach people how to recognize the commonalities that is the foundation which connects all forms of mediation together. Learn those three core commonalities and then learn to pick and choose which technique work for you in your life. One technique may be better for stress, another may be better to manifest loving kindness, another still may help you focus on an issue through contemplation.
None are right or wrong, that is for you to decide. Learn to weave them together so that you can create a practice that works for your unique style and life, rather than trying to fit your life into a 2,500 year old practice which, in reality, are the same. You will find it much easier to maintain your practice with less frustration when you do.
Be well and I hope this helps.
