The special features of this Sutra, which distinguish it from the other Mahayana writings, are, to give the most noteworthy ones: first, that the subject-matter is not systematically developed as in most other Sutras, but the whole book is a series of notes of various lengths; secondly, that the Sutra is devoid of all supernatural phenomena, but filled with deep philosophical and religious ideas concerning the central teaching of the Sutra, which are very difficult to comprehend, due to tersity of expression and to the abstruse nature of the subject-matter; thirdly, that it is in the form of dialogues exclusively between the Buddha and the Bodhisattva Mahāmati while in the other Mahayana Sutras the principal figures are generally more than one besides the Buddha himself who addresses them in turn; and lastly, that it contains no Dharanis or Mantrams—those mystical signs and formulas supposed to have a miraculous power. These singularities are enough to make the _Laṅkāvatāra_ occupy a unique position in the whole lore of the Mahayana school. In this characterisation of the _Laṅkāvatāra Sūtra_, I am referring to the first Chinese text of Guṇabhadra. The two later ones have three new chapters in addition: one of which forming the first chapter is a sort of introduction to the whole Sutra, giving the main idea of what is discussed in the body of the text itself; the remaining two are attached to the end. Of these, the one is a short collection of Dharanis, and the other which is the conclusion is known as the Gāthā chapter written throughout in verse and summarises the contents of the whole Sutra. It has, however, no paragraph making up the “regular ending” in which the whole congregation unites in the praise of the Buddha and in its assurance of observing his instructions. There is no doubt that these three new chapters are of later growth.
