Narayana
नारायण
Narayana is (a) as a sage: the second member of the tapasvi pair with Nara of the Badari hermitage; (b) as the Lord: a supreme name of Vishnu-Krishna. SB 1.2.4's invocation left the referent unsettled, so this entity carried a review flag. SB 1.3.9 resolves it: the Lord 'became the two sages Nara and Narayana' — the rishi Narayana is one of His assumed forms; flag cleared. In SB 1.2.26 'Narayana' unambiguously names the worshipped Lord — kept as an epithet of the 'krishna' entity; the two are deliberately not merged.

'tasv avatsit sva-srishtasu sahasram parivatsaran, tena narayano nama yad apah purushodbhavah' (SB 2.10.11).
At SB 3.4.22 the god Narayana and the blessed rishi Nara are described as 'loka-bhAvanau', the two who nurture the worlds, practising at Badari an austerity long and intense yet gentle: 'mR^idu tIvraM tapo dIrghaM tepAte loka-bhAvanau'.
'nara-narayanau risi bhutva' (SB 1.3.9) — the rishi Narayana is one of the two forms the Lord assumed; the name Narayana also belongs to the Lord Himself (SB 1.2.26), kept as an epithet of 'krishna', not merged here. Evidence: EXPLICIT (for the assumed rishi form).
