Sun worship

Although worship of demigods and nature are considered imperfect forms of religion, the sun is worshipped three times daily by second-initiated ISKCON devotees. Of course Krishna is the light of the sun (BGAII 7.8), so chanting the first mantra of gayatri isn’t delving into an inferior form of worship. Besides Vivesvar, the sun-god, is a great devotee of the Lord.
