yes Gem that's very true. i read somewhere he meditated to get the healing energy.infact everyone has the potential to achieve such self-attunement.
for example once i was meditating on Mother Durga,a goddess mainly prayed by hindus.i was saying a mantra of hers.only suddenly i sensed a powerful energy entering my crown.it was so intense.i felt like someone has attuned me to an energy.my symptoms for attuning is my stomach burns and it did burnt.
so it works for every of us.we have to beleive we can do it and most important beleive in ourselves.
lights of love,
