Without further delay, you must engage yourself in worshiping the lotus feet of the Supreme Personality of Godhead.

SB 4.8.19, Translation and Purport

My dear boy, whatever has been spoken by Suruci, your stepmother, although very harsh to hear, is factual. Therefore, if you desire at all to sit on the same throne as your stepbrother, Uttama, then give up your envious attitude and immediately try to execute the instructions of your stepmother. Without further delay, you must engage yourself in worshiping the lotus feet of the Supreme Personality of Godhead.

The harsh words used by Suruci to her stepson were true because unless one is favored by the Supreme Personality of Godhead one cannot achieve any success in life. Man proposes, God disposes. Sunīti, the mother of Dhruva Mahārāja, agreed with her co-wife's advice that Dhruva engage himself in the worship of the Supreme Personality of Godhead. Indirectly, the words of Suruci were a benediction for Dhruva Mahārāja, for because of the influence of his stepmother's words, he became a great devotee.
