In Bhagavad-gītā Lord Kṛṣṇa describes four kinds of pious men (su-kṛtinaḥ) begin to render devotional service unto Him – the distressed (ārto), the desirer of wealth (arthārthī), the inquisitive,( jijñāsuḥ), and he who is searching for knowledge of the Absolute (jñānī)’
catur-vidhā bhajante māṁ janāḥ su-kṛtino ’rjuna
ārto jijñāsur arthārthī jñānī ca bharatarṣabha (BG 7.16)
Dhruva Mahārāja was arthārthī Bhakta- desirous of wealth. He wanted a kingdom bigger than his grandfather Lord Brahmā. W
