Reference to Acharyas: Srila Rupa Goswami

Q. I have a question that is bothering me. I went last year to see MATA AMRITANDAMAYI also known as AMMA. She is a big devotee of Lord Krishna, always speaks of Lord Krishna's glories. She has the same message to humankind that our place is with the Lord and that we have to go back to Lord Krishna. My question is, I have seen devotees of amma chanting "om nama shivaya". So I am confused. What is the difference between the maha mantra and this mantra?

I hope you would enlighten me on this.

Q. The word 'sannyasi' means one in the renounced order of life, which also means being away from homely comforts. But how is that some sannyasis [gurus] hold administrative positions and material assets [fixed and liquid], accept material gifts and tend to lead an opulent life style [taking very opulent prasadam, jet traveling, doing shopping during foreign trips etc.] Is it that if one is spending 24 hours of his time in Krishna consciousness, he is exempted from the above rules?

Q. Who is Hyagriva avatar? Are there more than one?

Q. My question is how to break habits? How can one become serious and follow Srila Prabhupada's instructions more closely?

Retraction of bad habits was compared by Srila Bhaktivinoda Thakura as being synonymous to the jiva's returning back to the spiritual world, because in effect these bad habits are nothing but the binding effects of our long material association and past activities.
