What your North and South Node represents is what you already know, who you already are, and what you need to become, and what you need to work toward.
As a Libra North Node, in your past life, you had Aries tendencies. You could've been somewhat of a soldier or a person that is completely self-reliant and never relied on anyone else for anything and did everything on your own. You likely carry a lot of these qualities with you now, where you are incredibly self-sufficient, independent, able to master most tasks on your own, and you do not need help from other people to get things done. You are 100 % competent in whatever it is you do.
The thing is, you have already learned to be self-sufficient, reliable, and independent. These qualities you learned in your past life you carry with you into this life; however, in this life, you need to learn to develop the qualities of your North Node. The North Node indicates the qualities that you lack and what you need to learn to grow in this life.
A life path of partnership and compromise
Libra is the sign of partnerships, love, and marriage. With a Libra North Node, you need to learn that you do not need to do everything on your own and that other people are here and in your life to help you. You can relieve a lot of the pressure you place onto yourself by delegating duties to others so that they can assist you. The most challenging thing for you to realize is that you are not alone and that other people are here to help you.
Relationships are something that you do need to learn to develop and work on. You are likely entirely ok with being alone and being the lone wolf who does everything on their own. You do need to learn to move away from being happy alone and move towards wanting to be in a relationship or partnership or just merging your soul and energy with another person so that they can give you what they can offer you.
When you do stop wanting to do everything on your own, and you stop excluding everyone else around you with what you do, that is when things will start becoming a lot easier for you in your life. With an Aries South Node, a person can have the mentality of: "I am who I am, I have done what I have done to get where I am, and everybody else around me needs to accept me for who I am, or move on with life. ".
With the North Node in Libra, you need to learn that your actions and everything that you say and do affects the people around you. You can be oblivious to how what you do and what you say affects the people around you. You could most likely also not care how it affects the people around you and if you dont, then you aren't on the right path. It would help if you were on a path where you are entirely aware and completely considerate of how your actions and your words are affecting other people. When you become aware of how you affect other people, that is when you will be able to build the friendships and the partnerships that you need to grow and to learn what you need to learn in this life.
The things that you want, which are partnerships and relationships, are not going to come to you if you are going to be stuck in your Aries South Node way of doing things. You need to ensure that you think less about yourself and what you are going through, and more about other people and what they are going through. Once you start doing this, you will see you will begin to attract so many people into your life who will help you, who will bless you and who make your life so much easier for you to live. This will only happen if you stop being self-centered and selfish.
