Sayagyi U Ba Khin chanting the Tikapatthana, which is from the Abhidhamma, the first book of the Patthana, Tikapatthana, Kusalatikam, Panhavaro. It was recorded in Myanmar (Burma) in the 1960's on audio tape equipment available at the time.
Background hiss and electronic interference (especially the section in track 3 that temporarily obscures the chanting) are on the original tape and cannot be further filtered out without degrading the original quality of Sayagyi's chanting. It is 1 hour and 12 minutes, with eight tracks, each approximately 10 minutes each.
