3.29.37

rūpa-bhedāspadaṃ divyaṃ kāla ity abhidhīyate /
bhūtānāṃ mahad-ādīnāṃ yato bhinna-dṛśāṃ bhayam //

37. Again the Lord is called Kala or Time with reference to His wonderful form which becomes the source of all difference, the appearance of things; and from which arises fear, the fear of samsara, to the jivas presiding over the Mahat and other principles while having the notion of difference.
