At the end of chapter 15, the four Kumaras offered prayers to the Lord when He appeared at the gate. Now, in chapter 16 the Lord answers to them and offers a solution for the situation.
Jaya and Vijaya are eternal servitors of the Lord, but at the same time, they committed a mistake in stopping the sages. The Lord understood that the essence of the problem was that the Kumaras were anxious to see Him, and therefore he went personally there, accompanied by Lakshmi Devi to give them an audience. In his purport, Prabhupada mentions the case of Haridasa Thakura, who was also not allowed to enter the temple to see Lord Jagannatha in Puri. Just like the Lord came to see the Kumaras, He was also coming personally to see Haridasa Thakura as Sri Caitanya Mahaprabhu. As Prabhupada says, “The Lord is so merciful that even if there is some impediment for the devotee, He Himself manages matters in such a way that the devotee is not bereft of having audience at His lotus feet.”
