Tranquil Abiding is an advanced meditative state of mind that is attained through gradual meditative training focusing on the cultivation of mindfulness and meta-awareness. This paper will focus on the eighteenth-century Tibetan scholar Yeshe Gyaltsen’s manual on Tranquil Abiding. It involves introduction and analysis of the themes of Tranquil Abiding, such as the significance and objects of Tranquil Abiding, its relevance to Special Insight, mental hindrances, and factors which counter them. Illustrated will be how Yeshe Gyaltsen’s point of view, which he calls the Ganden tradition, is influenced by exceptional Indian Mahāyāna masters such as Nāgārjuna, Asaṅga, Śāntideva, Kamalaśīla, Atīśa Dipaṃkaraśrijñāna, and Tsongkhapa. Included will be a discussion of his understanding of amanasikāra.
