Srimad Bhagavatam Canto 04, Chapter 09, Text 45

SB 4.9.45

abhivandya pituh padav
 asirbhis cabhimantritah
nanama matarau sirsna
 sat-krtah saj-janagranih
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
Then Dhruva Maharaja, the foremost of all nobles, first of all offered his obeisances at the feet of his father and was honored by his father with various questions. He then bowed his head at the feet of his two mothers.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
It may be questioned why Dhruva Maharaja offered his respect not only to his mother but also to his stepmother, due to whose insults he had to leave home. The answer is that after achieving perfection by self-realization and seeing the Supreme Personality of Godhead face to face, Dhruva Maharaja was completely freed from all contamination of material desire. Feelings of insult or honor in this material world are never perceived by a devotee. Lord Caitanya therefore says that one has to be humbler than the grass and, He recommends, more tolerant than the tree to execute devotional service. Dhruva Maharaja, therefore, has in this verse been described as saj-janagranih, the foremost of noble men. The pure devotee is the noblest of all, and he has no feelings of animosity towards anyone. Duality due to animosity is a creation of this material world. There is no such thing in the spiritual world, which is the absolute reality.
