Sp VI 1298 uttānavihāra and Vinaya Texts III 404: an easy life). More correct is Kern's explanation ( Toev. sub voce ) which puts kullaka in this combination = kulla 2 (Sanskrit kaulya), thus meaning well-bred, of good family, gentlemanly; -saṇṭhāna consisting of stalks bound together, like a raft Ja II 406-408 (not correct Morris, JPTS 1884, 78).
