Janardana Sila

The form of the Lord described in this verse with distribution of different symbols — beginning from the lower right hand up and down to the lower left hand with lotus, wheel of a chariot, conchshell and club respectively — is called Janārdana, or the plenary portion of the Lord who controls the general mass.
(SB 2.2.8 purport)

The Supreme Personality of Godhead, Janārdana [Lord Kṛṣṇa], is the form to accept all the results of sacrifice. If He is not satisfied, then one’s labor for advancement is futile. He is the ultimate Self, and therefore one who does not satisfy Him certainly neglects his own interests.
(SB 3.13.13)

janārdana — O chastiser of the enemies (BG 11.51)
janārdana — O maintainer of all living entities. (BG 1.32-35)
janārdanaḥ — the controller of all living being (SB 3.7.35)
