Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Obeisances to You from the front, from behind and from all sides! O unbounded power, You are the master of limitless might! You are all-pervading, and thus You are everything!

Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Out of loving ecstasy for Krishna, his friend, Arjuna is offering his respects from all sides. He is accepting that He is the master of all potencies and all prowess and far superior to all the great warriors assembled on the battlefield. It is said in the Visnu Purana (1.9.69):

yo ’yam tavagato deva
samipam devata-ganah
sa tvam eva jagat-srasta
yatah sarva-gato bhavan

“Whoever comes before You, even if he be a demigod, is created by You, O Supreme Personality of Godhead.”
