The verse teaches that sincere devotion is supported by the divine: when a worshipper chooses a particular form to revere with faith, that faith is strengthened and stabilized toward the chosen object of worship.
In the Bhīṣma Parva’s didactic setting, Arjuna speaks about worship and faith, describing how a devotee’s intention to honor a particular form is met by a stabilizing reinforcement of that devotion.
