'substratum of existence'.

In the Com. there are enumerated 4 kinds:

• the 5 groups (khandha)

• sensuous desire (kāma)

• mental defilements (kilesa)

• karma

In the suttas it occurs frequently in Sn. (vv. 33, 364, 546, 728), and, with reference to Nibbāna, in the phrase "the abandoning of all substrata" (sabbūpadhi-patinissagga; D. 14).
