Book excerpt: This book elucidates the early Buddhist teachings and beliefs concerning meditaions and its role in the process to liberation. In a number of cases, the Buddhist canonical texts reject practices which they accept elsewhere. When these practices-sometimes rejected, sometimes accepted-correspond to what is known about non-Buddhist practices, the conculsion in then proposed that they are non-Buddhist practices which have somehow found their way into the Buddhist texts. A similar procedure enables one to choose between conflicting beliefs.
