Serving the Deity

Honor Gaṇapati, the remover of obstacles

Begin worship by honoring Gaṇapati, who clears away the obstacles to devotional service.

The Nectar of Devotion says the Deity should not be worshiped without first worshiping Gaṇapati, because he drives away the impediments to devotional service, and it notes that Gaṇapati himself worships the lotus feet of Lord Nṛsiṁha. Start your worship by asking for his blessing.
