Even if tortured, a pure devotee is never disturbed

[Bhakti Vikasa Swami]

Narayana-parah sarve na kutascana bibhyati (SB 6.17.28). A pure devotee of
Narayana is never afraid of any material danger. There are many examples of
devotees such as Prahlada Maharaja, who was tortured by his father but was not
at all afraid, although he was only a five-year-old boy. Therefore, following
the examples of Ambarisa Maharaja and Prahlada Maharaja, a devotee should learn
how to tolerate all such awkward positions in this world. Devotees are often
tortured by nondevotees, yet the pure devotee, depending fully on the mercy of
the Supreme Personality of Godhead, is never disturbed by such inimical
activities.
