References to text SB 6.17.28
SB 6.17.28: Devotees solely engaged in the devotional service of the Supreme Personality of Godhead, Nārāyaṇa, never fear any condition of life. For them the heavenly planets, liberation and the hellish planets are all the same, for such devotees are interested only in the service of the Lord.

“ ‘A person who is a devotee of Lord Nārāyaṇa is not afraid of a hellish condition, because he considers it the same as elevation to the heavenly planets or liberation. The devotees of Lord Nārāyaṇa are accustomed to seeing all these things on the same level.’
