A Vaisnava is always an object of envy for nondevotees, even when the nondevotee happens to be his father. To give a practical example, Hiranyakasipu was envious of Prahlada Maharaja, but this envy of the devotee was harmful to Hiranyakasipu, not to Prahlada. Every action taken by Hiranyakasipu against his son Prahlada Maharaja was taken very seriously by the Supreme Personality of Godhead, and thus when Hiranyakasipu was on the verge of killing Prahlada, the Lord personally appeared and killed Hiranyakasipu. Service to a Vaisnava gradually accumulates and becomes an asset for the devotee. Similarly, harmful activities directed against the devotee gradually become the ultimate cause of the performers falldown. Even such a great brahmana and mystic yogi as Durvasa was in a most dangerous situation because of his offense at the lotus feet of Maharaja Ambarisa, a pure devotee.
