10.44

The Buddha told Ānanda: "This sūtra is named 'Fixing Thought Without Moving'; uphold it as such. It is also named 'Contemplating the Urṇā-Mark of the Buddha'; uphold it as such. It is also named 'Contemplating the Parts of the Tathāgata's Body in Forward and Reverse Order'; it is also named 'Distinguishing the Parts of the Tathāgata's Body Pore by Pore'; it is also named 'Contemplating the Thirty-Two Marks, the Eighty Secondary Characteristics, and the Radiance of All Wisdom'; it is also named 'Ocean-like Samādhi of Buddha Contemplation'; it is also named 'Gateway to the Buddhānusmṛti-Samādhi'; it is also named 'The Form-Body of the Buddhas Adorned with Wondrous Flowers'; it is also named 'Sūtra on the Exquisite Form-Body Obtained as Fruitional Retribution, Explaining Morality, Concentration, Wisdom, Liberation, Knowledge and Vision of Liberation, the Ten Powers, the Four Fearlessnesses, and the Eighteen Distinct Qualities'. You must uphold it well and be careful not to forget or lose it."
