4.12.11

sarvātmany acyute 'sarve tīvraughāṃ bhaktim udvahan /
dadarśātmani bhūteṣu tam evāvasthitaṃ vibhum //

11. Having cherished intense devotion to Achyuta (the unchanging Lord) who is in the form of everything and is yet

different from all, he (Dhruva) saw the same all-pervading Lord present in his own self and in all other beings.
