Amitabha made 48 Great Vows and this was one of them :
“Provided I become a Buddha, if my light should be limited in measurement so that it could not illuminate a hundred thousand nayuta of kotis of Buddha-countries, then may I not attain the enlightenment.” (Vow 12, The Larger Sutra of Immeasurable Life)
This is probably one of the reasons why I enjoy meditating to Amitabha. When my eyes are closed and I let my body relaxed while I recite the name of Amitabha sincerely in my mind, I find myself receiving his Light. This Light, helps me to cleanse my mental and emotional clutter – allowing me to reset for the day; coming back fresher and more in tune with my heart and mind.
