When Dhruva Mahārāja became practically one in heaviness with Lord Viṣṇu, the total consciousness, due to his fully concentrating and his closing all the holes of his body, the total universal breathing became choked up, and all the great demigods in all the planetary systems felt suffocated and thus took shelter of the Supreme Personality of Godhead.
Srimad Bhagavata Purana

मूल श्लोकः
तस्मिन्नभिध्यायति विश्वमात्मनो द्वारं निरुध्यासुमनन्यया धिया । लोका निरुच्छ्वासनिपीडिता भृशं सलोकपालाः शरणं ययुर्हरिम्
tasminnabhidhyāyati viśvamātmano dvāraṃ nirudhyāsumananyayā dhiyā | lokā nirucchvāsanipīḍitā bhṛśaṃ salokapālāḥ śaraṇaṃ yayurharim
