 I received a message once that said spirit, god, or source, must not exist because that person had never heard a divine voice in their head, and it would be unfair and unbalanced if the divine only talked to a few people and not everyone. Certainly, this might seem logical at first, but actually, the matrix of reality is functioning perfectly. We have to think of it this way. Our brains are like tuning receivers that are capable of receiving signals from many dimensions at once, but that does not mean that we are necessarily tuned to receive them. Those who do not take the time to practice tuning themselves to the more subtle vibrations of the cosmos, such as through the art of meditation, reading holy scripture, or engaging in psychedelic ceremonies, will simply not be able to register those vibrations in their waking consciousness. Also, intention is another important key. Those who actively want to hear spirit will naturally find opportunities to do so.
