アバヤーカラグプタと菩提心の漏について――ヴァジラパーニ作LTṬとの関連――

抄録

This paper argues that the concept of sexual-yoga in the Āmnayamañjarī is influenced by Vajrapāṇi’s Laghusaṃvaraṭīkā (LTṬ). Vajrayāna Buddhists, specifically in the anuttarayoga stage, declared that their whole basic doctrine is based on and interrelated with rāga (kāma) caryā. Firstly, this paper elucidates the interpretation of aṣṭasamaya, the eight major applications of vows in the Cakrasaṃvaratantra, construed by Vajrapāṇi in his LTṬ. He applied the analytical concept of ‘inner and outer’ to this topic. He proclaims that in the case of ‘inner,’ emission of seminal fluid (bindu) must be prohibited unconditionally for the achievement of both mundane and supramundane accomplishments. In the case of ‘outer,’ however, practitioners should be allowed the emission of bindu for the experience of enjoyment and physical hygiene. Secondly, this paper argues that this important description by Vajrapāṇi in his LTṬ is cited in chapter 5 of Abhayākaragupta’s Āmnāyamañjarī.
