lokānāṁ loka-pālānāṁ
 mad bhayaṁ kalpa-jīvinām
brahmaṇo ’pi bhayaṁ matto
 dvi-parārdha-parāyuṣaḥ
Word for word: 
lokānām — in all the planetary systems; loka-pālānām — and for all the planetary leaders, such as the demigods; mat — of Me; bhayam — there is fear; kalpa-jīvinām — for those who live for a kalpa, or a day of Brahmā; brahmaṇaḥ — of Lord Brahmā; api — even; bhayam — there is fear; mattaḥ — from Me; dvi-parārdha — two parārdhas, totalling 311,040,000,000,000 years; para — supreme; āyuṣaḥ — whose duration of life.
Translation: 
In all the planetary systems, from the heavenly to the hellish, and for all of the great demigods who live for one thousand yuga cycles, there is fear of Me in My form of time. Even Brahmā, who possesses the supreme life span of 311,040,000,000,000 years, is also afraid of Me.
Purport: 

There are many statements throughout Vedic literature proving that even the great demigods fear the time potency of the Supreme Personality of Godhead. Even in the heavenly planets there is no relief from the miseries of material life. No conditioned soul can live eternally, as clearly demonstrated by the deaths of Hiraṇyakaśipu and other demons. Since even the demigods fear the time potency of the Personality of Godhead, one may easily conclude that Kṛṣṇa is the Absolute Truth and that He is eternally the supreme controller of everything and everyone. Lord Kṛṣṇa is the only real shelter.
