Unless that spiritual want is fulfilled, unless that spiritual relationship is reestablished, nobody can be happy. So in order to make us happy, Kṛṣṇa says that "Begin with little flower, little water, or little fruit, and try to offer Me."
mānaṁ janād aviduṣaḥ karuṇo vṛṇīte
yad yaj jano bhagavate vidadhīta mānaṁ
tac cātmane prati-mukhasya yathā mukha-śrīḥ

Just like if you decorate your face very nicely, how your face has become beautiful you cannot see. You cannot see. But as soon as you bring one mirror before your face, you'll see that in the mirror the reflection of your face is very nicely decorated. The same example is given here. We are reflection. We are reflection of God. Just like in the Bible it is said, "Man is made after God." God is not made after man. That is a mistake. The modern atheist class of men, they suggest that we manufacture a form of God according to our own form. Just like Kṛṣṇa and Rādhā, the picture is there. They allege that we have made a Kṛṣṇa form, maybe very beautiful, according to my form. But actually it is not. The Biblical truth is that man is made after God.Because we are sons of God, therefore God has got two hands, you have got also two hands. Just like your father has got two hands and you have got two hands, so you are made according to the body of your father, not that your father's body is made after your body. This is rationalism. Similarly, God's body is not made according to your body, but your body is made according to God's body. But this body is material; therefore we have to change. When we come to the spiritual platform, we get as good a body as that of Kṛṣṇa, which is eternal, full of bliss and full of knowledge. This is called Kṛṣṇa consciousness.
(Lecture on Srimad Bhagavatam--7:9:11-Montreal--17th. August, 1968).

He always accepted the good qualities of Vaiṣṇavas and never found fault in them. He engaged his heart and soul only to satisfy the Vaiṣṇavas.
It is a qualification of a Vaiṣṇava that he is adoṣa-darśī: he never sees others' faults. Of course, every human being has both good qualities and faults. Therefore it is said, saj-janā guṇam icchanti doṣam icchanti pāmarāḥ: everyone has a combination of faults and glories. But a Vaiṣṇava, a sober man, accepts only a man's glories and not his faults, for flies seek sores whereas honeybees seek honey. Haridāsa Paṇḍita never found fault with a Vaiṣṇava but considered only his good qualities.
(Sri Caitanya Caritamrta--1:8:62--translation and purport).

The great wizards who were able to assume any form were engaged by the King of Bhoja, Kaṁsa, to kill Kṛṣṇa, but in the course of His pastimes the Lord killed them as easily as a child breaks dolls.
The atheist Kaṁsa wanted to kill Kṛṣṇa just after His birth. He failed to do so, but later on he got information that Kṛṣṇa was living in Vṛndāvana at the house of Nanda Mahārāja. He therefore engaged many wizards who could perform wonderful acts and assume any form they liked. All of them appeared before the child-Lord in various forms, like Agha, Baka, Pūtanā, Śakaṭa, Tṛṇāvarta, Dhenuka and Gardabha, and they tried to kill the Lord at every opportunity. But one after another, all of them were killed by the Lord as if He were only playing with dolls. Children play with toy lions, elephants, boars and many similar dolls, which are broken by the children in the course of their playing with them. Before the Almighty Lord, any powerful living being is just like a toy lion in the hands of a playing child. No one can excel God in any capacity, and therefore no one can be equal to or greater than Him, nor can anyone attain the stage of equality with God by any kind of endeavor. Jñāna, yoga and bhakti are three recognized processes of spiritual realization. The perfection of such processes can lead one to the desired goal of life in spiritual value, but that does not mean that one can attain a perfection equal to the Lord's by such endeavors. The Lord is the Lord at every stage. When He was playing just like a child on the lap of His mother Yaśodāmayī or just like a cowherd boy with His transcendental friends, He continued to remain God, without the slightest diminution of His six opulences. Thus He is always unrivaled.
