Translation:
Securely binding up His clothes and tying back His curly locks, Lord Krsna addressed the elephant-keeper with words as grave as the rumbling of a cloud.
Purport:
Lord Krsna was obviously preparing for a fight. According to Srila Visvanatha Cakravarti Thakura, the Lord put aside His jacket, tightened His belt and tied back His hair.
