Abstract

                This thesis has 2 objectives.  Number one, to study the Vipassanūpakilesa in the Theravada Buddhist Scriptures. And number two, to study the Vipassanūpakilesa during the Practicing of Vipassanā-Bhāvanā. The Thesis took information from the Theravada Buddhist Tepitaka, Scriptures, Tika and related commentaries.  Data taken were then processed and approved by thesis advisers and Vipassanā-Bhāvanā specialists.

                The  researcher found that Vipassanūpakilesa is what deteriorating the Vipassanā process.  Vipassanūpakilesa has 10 kinds, namely the Obhāsa (luminous aura), the Ñāṇa (knowledge), the Pīti (unprecedented joy), the Passaddhi (tranquility), the Sukha (bliss pleasure), the Adhimokkha (resolution), the Paggāha (exertion), the Upaööhāna (firm mindfulness), the Upekkhā (equanimity) and the Nikanti (delight of the above 9).

                Vipassanā-Bhāvanā is the intensive training in Sīla, Samādhi and Pañṇa towards Purification.  It practically requires mindfulness in the body, the feelings, the consciousness and the Dhamma together with essential criteria of being Perseverant, that is, being Sampajāno and mindful at all time.  The meditator should not give up contemplating when encounter phenomena.  He should be an Āraddha-Vipassaka (the beginner).  When he comes across some surprising circumstances among  these 10 Vipassanūpakilesas,  which  delude him as already possessing or attaining   Enlightenment,  his  Vipassanā  Ñāṇa  may be hindered and wisdom unprogressive.  However, if the meditator persists on “noting” them correctly, which is called  Yonisomanasikāra, he will be able to overcome these Illusive Vipassanūpakilesas.
