While the Buddha Amitabha recitation method leads one to the pureland, this video is an account of reciting Namo Amitahba bringing about other more mundane benefits.
It was mentioned in the video that some benefits included the warming of cold feet, healing of a sick dog, and dispelling of poison in a lady.
The benefits are said to be unfathomable.
Feeling troubled with anything at all? This is how one can practice: pronounce A-mi-tuo-fo repeatedly for 10 minutes.
As Master Hua said, first comes the practice, then comes the faith.
Try it.
Sometimes you just need this small and short karmic connection...
