" 'A person who is devoted to the Supreme Personality of Godhead, Narayana, is not afraid of anything. Elevation to the heavenly kingdom, condemnation to hell and liberation from material bondage all appear the same to a devotee.'
This verse is quoted from Srimad-Bhagavatam (6.17.28). Elevation to the heavenly planets, liberation from material bondage, and condemnation to hell are all equal to the devotee. The devotee's only desire is to be attached to the lotus feet of Krsna and to engage in His transcendental loving service.
