Bhagavad Gita, Chapter 5, Verse 26

Released from lust and anger, the heart controlled, the Self realised, absolute freedom is for such Sannyâsis, both here and hereafter.

This isn't something that only pays off eventually, it's described as real freedom available right now, not just later.

The phrase 'here and hereafter' matters, this isn't a promise deferred to some future life. Genuine inner work is described as changing something real in the present, not just banking credit for later.
