Some of the talks and writings on Vipassana are difficult to prove to be true although they have followers. In order to learn the truth in line with canonical texts, I studied works of Mahasi Sayadaw who is highly respected by scholars for his well versed knowledge and practice. I found many remarkable solution he made to the today Vipassana complexities. There are considerable amount of books by Mahasi Sayadaw such as the discourse on Paticca-samuppada, the discourse on Silavanta, the discourse on Bhara, the discourse on Tuvataka, the discourse on Dhamma-cakka, the discourse on Sallekha, the discourse on The Eight-fold Noble Path to Nibbana, the discourse on Ariya-vasa, the discourse on how to practice Vipassana, the discourse on Anatta-lakkhana, the translation of Satipatthana Sutta, the discourse on Vammika, the discourse on the Basic Vipassana, and so on. I found many of his remarkable solutions to the today Vipassana complexities.
