1. Formidable enemies of devotees

    A devotee’s most formidable enemy is association with women in an enjoying spirit. Association with nondevotees is also condemned because it is also a formidable enemy on the path of devotional service. One has to fully surrender unto the lotus feet of Krsna and give up attraction for women and nondevotees.
