Simply reciting Amitabha Buddha’s name may not be enough for Pure Land practice. It is necessary to combine Pure Land practice with the study of Dharma because while some people may have great reverence for, and faith in, Amitabha Buddha, and on this basis are able to succeed in this practice and go to Amitabha’s Pure Land at the time of their death; for many others, in the midst of their recitation of Amitabha Buddha’s name, they find themselves experiencing many doubts and questions about the validity of such recitations. We must study the Dharma to resolve these questions. If we are reciting the Buddha’s name and at the same time our mind is plagued by doubts about the practice then this is a big obstacle.
