Because I believe it's good to pass on and share techniques I find success with, I'd like to highlight the power of this mantra for those that aren't aware of it. Hands down the biggest improvement in my health is down to morning and nightly recitations of this mantra to Lord Dhanvantre, the Celestial Healer.
I'd recommend this for people who struggle with chronic health conditions for which there is no singular simple medical solution. Obviously, don't ignore science and medicine!
I'd never found a doctor that prescribed me anything, other than "Try and eat healthily and get exercise when you can", so of course, I looked at alternative solutions to see if I could speed things along.
I experienced a health issue in 2014 and hadn't been feeling 100% ever since. The biggest lingering condition I have suffered with ever since that time has been chronic fatigue. Within the first month of making this mantra a part of my daily spiritual practice, the problems I'd struggled with on a daily basis for the past two years have dramatically decreased.
If you are completely new to the practice of mantra recitation and are interested in exploring, I highly recommend you read "Healing Mantras" by Thomas Ashley-Farrand, which is a great introduction to the subject for a Western audience, purchase yourself a set of 108 mala beads (if you take to mantras like I have, they will likely become one of your most cherished, well loved and used spiritual and magical tools).
I tried praying novenas to St Raphael, and daily prayers to a healing aspect of my main Goddess, but I must say, this mantra alone has been doing the work for me. As with any spiritual or magical practice from a tradition other than your own, always be sure to show great respect to the culture from which it derives, and always show respect to any deity or spiritual being. Dhanavantre has been helping me so much, I will probably consult some of my Hindu friends for instruction in how to perform a simple puja ceremony for him to say thank you properly. I continue with this mantra daily and continue to be grateful.
