Hi Niamh and Karoliina
I can only share what I've read, but many of the readings say quite similar things about how souls are "organized."
Souls organize themselves into groups. You could see these as support groups. Souls organize themselves into Families, Groups, Clans, Nations, and Grand Nations. There are seven souls in a Soul Family and seven families in a Soul Group, and seven groups in a Soul Clan, and so on. Eventually, you will work with most members of your Soul Clan, that is 343 individual souls. However, for those of you who are teachers, you will more than likely reach your Soul Nation or Grand Nation, which totals almost 17,000 souls.
The majority of your relationships, close friendships, and associations will be with souls who are from your Group of 49 souls. However, this is not always the case. The more you advance in terms of acceptance (love), the more skilled you will become at working with individuals who have a different energy signature than yourselves. What we mean by energy signature is the following: each Soul Group will be working towards a particular goal.
For example, many members of one Soul Group could be concerned with communication and teaching, another with healing, another with courage, another with self- acceptance. This does not mean that each of you will manifest in the same way and lead identical lives, but it does mean that the essence of your lives will be very similar. You will have similar ideals, aspirations, likes, and dislikes. The people you are most drawn to are almost always members of your Soul Family, Group, Clan or Nation, but as with everything, there are exceptions to the rule.
A Soul Family will work together for many, many lifetimes. Sometimes a Soul Family will regroup and different alliances will be made. This is rare, but it happens. In addition, the entire Soul Family will be involved in decision making regarding future lifetimes and will assist you in assessing your achievements in a lifetime just past. Your Soul Family is always there for you. For the most part, not all members of a Soul Family are incarnate at the same time. Those members who are not incarnate act as spirit guides during the physical life of the one who is incarnate. They can visit you in dreams, inspire you with thoughts, or in some cases, speak to you directly during meditation. Many of the spirit guides that have presented themselves to humans are indeed discarnate souls who are members of the individual's Soul Family. However, many of the Master Teachers that present themselves to humans are either members of the individual's Nation or Grand Nation and are souls whose Earth experience is complete. At times these Master Teachers can be souls that are even broader and vaster than this.
A soul mate is any soul that is a member of this broader group and anyone that touches your life. The net effect of a soul mate on your life will always be positive, even if you cannot see it at the time. For example, many have the notion that a soul mate relationship will be the ideal relationship, full of harmony and love. However, a relationship with a soul mate is likely to be challenging!
The whole point of a soul mate turning up in your life is to show you to yourself. That is the purpose of all human relationships. You learn through viewing in the mirror. The Law of Attraction works in every aspect of your life, and therefore each person drawn into your life is there through vibration, and nothing else. They are present because your vibration and their vibration are matched in some way.
Hope that helps!!
