妙法蓮華經玄贊 7.53

7.53

贊曰：子獲得也。有為功德，名為珍寶。無為真如慈悲心等，名為舍宅。又識達本識當成鏡智，亦知一切三界眾生皆已舍宅及獲珍財，故生歡喜。

The Commentary says: The son obtains it. Conditioned merits are called rare jewels. Unconditioned tathatā, the mind of loving-kindness and compassion, and so forth, are called houses and residences. Furthermore, understanding the fundamental consciousness (ālaya-vijñāna) as that which will become the mirror-like wisdom, and also knowing that all sentient beings of the three realms have already obtained the house and obtained rare wealth, he therefore generated joy.
