He is sometimes called the Cakrī

The Lord’s cakra is the symbol of the power by
which the Lord controls the whole manifestation.

For material creation, Lord Kṛṣṇa’s plenary expansion assumes three Viṣṇus. The first one, Mahā-Viṣṇu, creates the total material energy, known as mahat-tattva. The second, Garbhodakaśāyī Viṣṇu, enters into all the universes to create diversities in each of them. The third, Kṣīrodakaśāyī Viṣṇu, is diffused as the all-pervading Supersoul in all the universes and is known as Paramātmā, who is present even within the atoms. This material world is a temporary manifestation of one of the energies of the Lord. All the activities of the material world are directed by these three Viṣṇu expansions of Lord Kṛṣṇa. Anyone who knows these three Viṣṇus can be liberated from material entanglement. (Bg 7.4 : PURPORT)

A yogī who is practicing meditation on the Supersoul sees within himself the plenary portion of Kṛṣṇa as Viṣṇu—with four hands, holding conchshell, wheel, club and lotus flower. The yogī should know that Viṣṇu is not different from Kṛṣṇa. Kṛṣṇa in this form of Supersoul is situated in everyone’s heart. Furthermore, there is no difference between the innumerable Supersouls present in the innumerable hearts of living entities. Nor is there a difference between a Kṛṣṇa conscious person always engaged in the transcendental loving service of Kṛṣṇa and a perfect yogī engaged in meditation on the Supersoul. The yogī in Kṛṣṇa consciousness—even though he may be engaged in various activities while in material existence—remains always situated in Kṛṣṇa. (Bg 6.31 : PURPORT)

Lord Viṣṇu has four hands, and each hand holds a particular item—either a conchshell, wheel, club or lotus flower. Of these four emblems, the cakra, or wheel, is the chief. Lord Kṛṣṇa, being the original Viṣṇu form, has only one emblem, namely the wheel, and therefore He is sometimes called the Cakrī. The Lord’s cakra is the symbol of the power by which the Lord controls the whole manifestation. (SB 3.1.23 : PURPORT)
