It is also titled '''''Liṅga-avatāraratnasūtramLaṅkāvatāraratnasūtram''''' (''The Jewel Sutra of the Entry into LingaLaṅkā,'' [[Guṇabhadra|Gunabhadra's]] Chinese title: 楞伽阿跋多羅寶經 léngqié ābáduōluó bǎojīng) and '''''Saddharmaliṅga-avatārasūtraSaddharmalaṅkāvatārasūtra''''' (''The Sutra on the Descent of the True Dharma into LingaLaṅkā'').<ref name=":0">{{Cite web |title=Laṅkāvatārasūtra - Buddha-Nature |url=https://buddhanature.tsadra.org/index.php/Texts/La%E1%B9%85k%C4%81vat%C4%81ras%C5%ABtra |access-date=2022-12-28 |website=buddhanature.tsadra.org}}</ref> A subtitle to the sutra found in some sources is "''the heart of the words of all the Buddhas''" (一切佛語心 yiqiefo yuxin, Sanskrit: ''sarvabuddhapravacanahṛdaya'').<ref name=":16" />
The ''LaṅkāLaṅkāvatāra'' recounts a teaching primarily between [[Gautama Buddha]] and a [[bodhisattva]] named Mahāmati ("Great Wisdom"). The sūtra is set in mythical [[Lanka|Laṅkā]], ruled by [[Ravana|Rāvaṇa]], the king of the [[rakshasa|rākṣasas]]. The ''Laṅkāvatāra'' discusses numerous [[Mahayana]] topics, such as [[Yogachara|Yogācāra]] philosophy of mind-only (''cittamātra'') and the [[Trisvabhāva|three natures]], the [[Eight Consciousnesses|''ālayavijñāna'']] (store-house consciousness), the inner "disposition" (''gotra''), the [[buddha-nature]], the [[luminous mind]] (''prabhāsvaracitta''), [[Śūnyatā|emptiness]] (''śūnyatā'') and [[Buddhist vegetarianism|vegetarianism]].<ref name=":3">{{Cite web |last=Nguyen |first=Dac Sy |date=2012 |title=Buddha-nature (as Depicted in the Lankavatara-sutra), Introduction |url=https://www.wisdomlib.org/buddhism/essay/buddha-nature-lankavatara-sutra/d/doc1145025.html |access-date=2022-12-29 |website=www.wisdomlib.org |language=en}}</ref><ref name=":0" />
The ''Liṅga-avatāraLaṅkāvatāra Sūtra'' was often quoted and paraphrased by Indian philosophers like [[Chandrakirti]] and [[Shantideva]], and it also figured prominently in the development of [[East Asian Buddhism]].<ref>Ruegg, David Seyfort, ''<nowiki>''The Literature of the Madhyamaka School of Philosophy in India,''</nowiki>'' Otto Harrassowitz Verlag, 1981, p. 7.</ref><ref>Christian Lindtner. ‘The Laṅkāvatārasūtra in Early Madhyamaka Literature’.

Various scholars like [[D. T. Suzuki|DT Suzuki]] and Takasaki Jikido have noted that the text is somewhat unsystematic and disorganized, resembling the [[notebook]] or [[commonplace book]] of a Mahayana master which recorded important teachings.<ref>Karl-Heinz Golzio (2010).
