Śrīla Bhakti Rakṣak Śrīdhar Dev-Goswāmī Mahārāj describes the type of exclusive adherence Śrī Vrajendra Nandan Kṛṣṇa expects from His devotees.
“I distribute truth by instalment, according to the capability of those to whom I give. One will have such fine understanding as to understand, as to know, as to feel, that this is his order, but to a particular group. But more intelligent and higher minded persons may cross those rulings and advance further.
“There are so many scriptures to be ignored, so many sādhus of that level to be ignored, and even the society and well wishers, well wishers of different interests—everything should be ignored if you want Me as Kṛṣṇa, Svayaṁ Bhagavān Kṛṣṇa, especially in Vṛndāvan, Vraja. I can’t tolerate any partner of any shade in My dealings with everyone. No partnership. I am the absolute enjoyer. I cannot tolerate any partnership, even with whom you should have some obligation, such as the guru section, pīta, mātā, the relatives, the parents, so-called superiors. None I can tolerate. If you have any partnership then I am not there. I am not there. I want cent per cent. If you want Me then I want to have cent per cent in quality. You may have to attend those duties but outwardly, as a show. You may make a show in attending to those duties, but I want the innermost heart. There I am. I am there. Otherwise you will have to come to My outer expression; I will engage you with one of so many other forms of mine. But Vrajendra Nandan, if you want Vrajendra Kiśor, you may have no other partner. Hare Kṛṣṇa.
sva-janam ārya-pathaṁ cha hitvā
bhejur mukunda-padavīṁ śrutibhir vimṛgyām
(Śrīmad Bhāgavatam, 10.47.61)
“The Vedas, the rulings, law books, religious law books also cannot express, but they’re aiming at such a thing. Śrutibhir vimṛgyām, all the revealed truth, revealed expressions are aiming towards this but can’t express it fully. That is, My nature is such. I am most selfish in that respect, so selfish that even the scriptures cannot measure it. They fail to measure and express, that I am so selfish.”
But you will try to understand that He is your absolute good.
