Planet Earth was designed as a platform for the evolution of human souls.
Human souls are at a higher level than animals.
The lifestream of an animal can eventually progress to the human level.
Nevertheless, animals are at a lower level of spiritual evolution than humans.
Therefore, animals are subservient to humans and the key to their growth is to serve humans.
One of the ways in which animals progress is in their interaction with humans, such as being domesticated animals or pets.
Especially pets can progress by imitating the qualities and personalities of their owners.

However, please do not misinterpret this to mean that I am saying people should have pets in order to help animals grow.
However, there is a very fine line to be found in the treatment of animals, and people will be held accountable for mistreating animals.
You currently see horrendous misuses of animals by human beings.
The cause is that human beings have become trapped in the lower state of consciousness, the carnal mind.
That same state of consciousness also causes human beings to commit horrendous atrocities against other human beings.
The cause of all inhumane treatment of animals is the lower state of consciousness.
Make it your foremost priority to seek the Christ consciousness, and you will become much more effective in your work for improving the treatment of animals.
