I agree with Humanoid that in order to manifest something, you must truly believe it. But if you are wanting to raise your vibration in order to attract positive/high vibration outcomes, you do have to consider what you eat. If you think about the tremendous pain and fear the animals experience during their confinement and slaughter – that is the energy their bodies will vibrate with, and is what you ingest every time you ingest their flesh. Your vibration will only be able to get to a certain point. I can tell you when I stopped ingesting animal products, it was amazing the difference in my spiritual path – almost like a cleansing. That is my experience anyway. Best of luck to you!
