In plain words
The poet, to those who take other gods for the cause of all: It is the Lord hued like the waters of the surging sea who made men with no distinction of knowledge enter the six creeds [Buddhist, Nyāya, Vaiśeṣika, Jain, Sāṅkhya and Yoga]. If he but stands aside, then at that very moment the swagger of whichever gods, every kind of rite performed for them, and every invocation of them, will vanish.
