SB 9.5.26, Translation and Purport

Śrīla Śukadeva Gosvāmī continued: Thereafter, because of his advanced position in devotional life, Mahārāja Ambarīṣa, who no longer desired to live with material things, retired from active family life. He divided his property among his sons, who were equally as qualified, and he himself took the order of vānaprastha and went to the forest to concentrate his mind fully upon Lord Vāsudeva.

As a pure devotee, Mahārāja Ambarīṣa was liberated in any condition of life because, as enunciated by Śrīla Rūpa Gosvāmī, a devotee is always liberated.
