There are many Beings in the Higher Realms, all with Their different remits, working on Their Own or as a Collective.
As you would imagine, there are a multitude of tasks to consider when in Our position.
When looking at the Earth and all its diversity, you cannot give everyone the same teachings. Think of all the different religions in the World today, with each religion split into different beliefs too.
The idea of taking a human body is to somehow, while you are still alive, find your way back to the Source (God). How you do this depends very much on where you live, how you are brought up, your beliefs and so on. People will be attracted to different types of teaching.
Once someone has been Initiated into the Light and Sound they are then able to follow their own Truth back to the Source. They are able to experience Love, Peace and Stillness beyond anything they have ever dreamt of. But not everyone will want this; they will consider meditation perhaps as being boring or weird. A person who Meditates can, and does, still have fun in the World. The difference is that they have an anchor when things get tough. They are also able to see life from a different perspective and become more wise.
Our job in the Higher Realms is to try to help people reach their highest Potential whilst in human form. How we do that is to give out different teachings in the hope that people will achieve this.
The basic purpose of any life is to Love and to Learn. The ‘Richness’ of a person’s life truly depends on understanding fully the reason for this.
