When a psychic attempts to attune to the future numbers they are flooded with the conflicting energy patterns of all those playing.

One of the objectives of yoga practices is to maximize health in order to prolong healthy life in order to accomplish as much as possible spiritually. The choice to eat or avoid certain foods is an individual matter. Many people have subtle allergies to some foods, and each metabolism is different. I have been a pure vegetarian at certain periods of my life, but I now eat chicken and fish, but not red meat. This is mostly a personal issue of what I have found works best for my body, and not a recommendation for others.
