1. Cremation is better.

The reason for this is simple: At death, physical matter, meaning the composition of the body itself, still remains alive in some form for a long time after "death". There are biological parts that are linked to our spiritual counter-parts that will remain active for days, weeks, maybe even months after. This can cause a person to still be linked, or perhaps I should call it chained, to the physical body after death.

In worst case, what this means, is that a person may still find himself within his physical body after death. In a sense, he will find himself "paralyzed" and, due to his body being dead, unable to move or speak in any way no matter how much he tries. He may not realize that he is dead. Many people are buried while still "awake", they are conscious and aware, as they are put into the ground. Needless to say, this can be quite traumatizing. People may be terrorized believing they are not dead, but just in a sort of coma, buried alive, until eventually the body rots and the spirit finally gets free.

With cremation, the spirit is set completely free immediately, as all the organic and active material of the physical body is destroyed and rendered to dust. A Soul will not remain chained to a cremated remain. The person will immediately understand, due to obvious reasons, that he is actually dead and free from the physical body, and now in spirit form, ready to move on.

Thus, personally, I would recommend cremation, since it assures a proper transmission from physical matter into spirit shortly after the moment of death.

2. It is fine for people to eat meat.

Meat is a natural part of humans food chain and way of life. Live a generally healthy lifestyle, take care of yourself, and you will be fine. Spiritually speaking, there are no problems associated with consumption of meat, and in the end, anything we eat come from other live beings, whether animals, plants, fruits or vegetables. All food are, or have been, conscious entities with their own awareness.
