A person who has proceeded far enough along the path of ascension eventually feels at one with not only humanity but with the entire animal kingdom and all of nature. Animals are loved and respected as intelligent beings and as their sisters and brothers. As a result of this, the person may experience emotional issues while consuming meat. For example, they may feel a strong wave of sadness or even be brought to tears while consuming meat. The thought of consuming a being that was once alive and then killed for consumption becomes difficult to bear. Compassion for the animal that is being consumed may also be experienced.
Eventually the whole concept of a reality system having been created in which humans and animals need to kill one another in order to survive may begin to bother a person who is far along the path of ascension. The whole system of violence and brutality of the 3rd dimension Earth becomes harder and harder to bare. Wanting to live in a place that is in a high enough dimension in which society does not kill others in order to survive may become a strong desire. This should come as no surprise, as it has been said that in the higher dimensions beings consume pure energy or light rather than food. Similar to this would be the 3rd dimension Earth equivalent of getting enough exposure to sunlight in order for the human body to contain enough Vitamin D.
If you still eat meat, it does not necessarily mean that you are not ascending or that you will not ascend. Similarly, if you still eat meat, it also does not necessarily mean that you are not evolved spiritually. This article simply mentions some of the symptoms that people who are on the path of ascension have been experiencing.
Therefore, if you are on the path of ascension, and all of the sudden, you find yourself not desiring meat anymore, you now understand why. Our energy vibration is increasing, and we eventually do not need to consume the lower vibrational foods any longer. We begin to crave foods that are more in alignment with our increasing energy vibration.
