SB Canto 2
A person with a broader outlook can see that the ultimate authority is the Lord, even for material benefits.
SB 2.3.10, Purport: Udāra-dhīḥ means one who has a broader outlook. people with desires for material enjoyment worship small demigods, and such intelligence is condemned in the Bhagavad-gītā (7.20) as hṛta jñāna, the intelligence of one who has lost his senses. One cannot obtain any result from demigods without getting sanction from the Supreme Lord. Therefore a person with a broader outlook can see that the ultimate authority is the Lord, even for material benefits. Under the circumstances, one with a broader outlook, even with the desire for material enjoyment or for liberation, should take to the worship of the Lord directly. And everyone, whether an akāma or sakāma or mokṣa-kāma, should worship the Lord with great expedience. This implies that bhakti-yoga may be perfectly administered without any mixture of karma and jñāna. As the unmixed sun ray is very forceful and is therefore called tīvra, similarly unmixed bhakti-yoga of hearing, chanting, etc., may be performed by one and all regardless of inner motive.
SB Canto 5
Māyā is not the ultimate authority for the creation of this material world. Māyā acts on behalf of Kṛṣṇa.
SB 5.2.7, Purport: While undergoing severe penances in the forest, Āgnīdhra was captivated by the movements of Pūrvacitti, the girl sent by Lord Brahmā. As stated in Bhagavad-gītā, kāmais tais tair hṛta jñānāḥ: [Bg. 7.20] when one becomes lusty, he loses his intelligence. Therefore Āgnīdhra, having lost his intelligence, could not distinguish whether Pūrvacitti was male or female. He mistook her for a muni-putra, the son of a saintly person in the forest, and addressed her as muni-varya. Because of her personal beauty, however, he could not believe her to be a boy. He therefore began studying her features. First he saw her two eyebrows, which were so expressive that he wondered whether he or she might be the māyā of the Supreme Personality of Godhead. The words used in this connection are bhagavat-para-devatāyāḥ. Devatāḥ, the demigods, all belong to this material world, whereas Bhagavān, the Supreme Personality of Godhead, Kṛṣṇa, is always beyond this material world and is therefore known as para-devatā. The material world is certainly created by māyā, but it is created under the direction of para-devatā, the Supreme Personality of Godhead. As confirmed in Bhagavad-gītā (mayādhyakṣeṇa prakṛtiḥ sūyate sa-carācaram [Bg. 9.10]), māyā is not the ultimate authority for the creation of this material world. Māyā acts on behalf of Kṛṣṇa.

In that trust you must be very careful to make sure that my name is registered there as the founder-acarya and that I am to be the ultimate authority.
Letter to Kurusrestha -- Bombay 28 December, 1974: Regarding your farm, that will be very nice. But be sure to maintain your temple there in Denver. It is a very beautiful temple. Do not loose it. Also your idea of forming a trust between ISKCON and the leading men in the Indian community is approved by me. That is very nice. Let the Indians take part in our movement and help us to push on this mission of Sri Caitanya Mahaprabhu. In that trust you must be very careful to make sure that my name is registered there as the founder-acarya and that I am to be the ultimate authority. In other words, in any case of necessity of vetoing or cancelling any decision made by the other trustees, I should be able to do like that. My decision should over-rule all the other trustees combined.
