SB 9.18.50
tam eva hrdi vinyasya
vasudevam guhasayam
narayanam aniyamsam
nirasir ayajat prabhum

Without material desires, Maharaja Yayati worshiped the Supreme Lord, who is situated in everyone’s heart as Narayana and is invisible to material eyes, although existing everywhere.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
King Yayati, although externally seeming very fond of material enjoyment, was internally thinking of becoming an eternal servant of the Lord.
