Modes of Material Nature: Mode of Ignorance

Q. 1. In our religion it is stated that we should not eat meat. However what is the difference between eating plants and eating animals? Either way we are killing a living entity. The only difference I see is that animals can voice their agony while plants cannot.

Q. If someone say's even Hitler was vegetarian but he created so much havoc. How can one support the argument that vegetarian food results in pleasant thoughts.

Q. Why don't I like to study or, in general, do my prescribed duty? I do not enjoy doing any work. Why do I feel great pain while doing that?  I see that other friends and devotees easily absorb their minds in their works and do it but I am not able to absorb my mind. I do not find in myself any creativity.

Please tell what the reason is for this and cure for it.

This strong aversion or inertia for action should be understood to be the effect of material infection, due to tamo-guna. Krishna describes the strange effects of this mode of nature in BG Chapter 14. This inertia is opposite to the nature of spirit, for the spirit soul by nature is always active.

There are stories about Christian mystics who fell victims to demons while thinking that they communicate with God. For example, during deep prayers and austerities, some of them smelled heavenly fragrance and a divine being appeared to them, speaking seemingly about spiritual truths, but in fact that "angel" was misleading that ardent Christian mystic. Is something like that possible in Vaishnavism? How to recognize who is on the other side of the line?
