Connection with Guru is connection with his bhava.
Service is a privilege which is extended to a conditioned soul by the mercy of Guru.
My role as guru is not the same as Srila Prabhupada's role as guru because he is uttama adhikari.

Spiritual master is representative of God. Similarly, king is also representative of God. The father is also representative of God. These are the statements of the sastras. Because they will guide. The king will guide. The spiritual master will guide. The father will guide. What is that guidance? That guidance is how one can become Krishna Conscious by education, by culture.
The Lord in human society does what is the duty of everyone, but sometimes He does something extraordinary and not to be imitated by the living being. His acts of evening prayer as stated in Srimad Bhagavatam must be followed by the living being, but it is not possible to follow His mountain-lifting or dancing with the gopis. One cannot imitate the sun, which can exhaust water even from a filthy place; the most powerful can do something which is all good, but our imitation of such acts will put us into endless difficulty. Therefore, in all actions, the experienced guide, the spiritual master, who is manifested mercy of the Lord, should always be consulted, and the path of progress will be assured.
