五法

In Laṅkāvatāra Sūtra, all Dharmas are classified into five categories:

1. Form ( 相 ) -- all matters, whether sentient or non-sentient, has different forms, shapes, states, marks, or the like.
2. Name ( 名 ) --A name is given to each Dharma in accordance with its form, functions, characteristic, etc.
3. Differentiation ( 分別 ) -- The relative standard for big or small, good or bad, etc. is established for our reference, differentiation, and recognition.
4. Right Wisdom ( 正智 ) -- It refers to the wisdom of the mental functions with non-outflow mind/consciousness ( 無漏心 ). All false forms and names of Dharmas are regarded as provisional and impermanent. It is also the wisdom that contemplates the ultimate truth -- Middle Path.
5. Thusness ( 如如 ) -- the state of mind attained by Right Wisdom. As the mind is in the state of Nirvāṇa, not even one single Dharma is attained. This is so called Thusness, which is the true nature of Dharma, the true noumenon, or the Absolute.

The first three are Conditioned Dharmas ( 有為法 ), while the last two are Unconditioned Dharmas ( 無為法 ).
