Lunar Nodes creates fated and karmic circumstances, when it gets activated - - that house that it touches gets more alive. It brings events and happenings to us for new beginnings or endings alike. It really depends... and it also varies depending on the sign it is in for more details. However, on this topic... we look into the activation on the house itself, regardless of the sign - this way, we get to know what situations and happenings in our life might get triggered so we can make preparations and have awareness on what may come or arise to the future.

I will be sharing information by house axis - north node/south node. You will need to get updated where are the "current" lunar nodes of the year for you to know the sign it is in and the house it gets activated.
For example: Currently of 2021, the Lunar Nodes are in North Node in Gemini and South Node in Sagittarius. For me personally, this is on my 9/3 house axis. It may be different for you, you will need to look where your Gemini is and where Sagittarius is. For the year of 2022, it will be on North Node in Taurus and South Node in Scorpio and that is the current activation we look on.
So, look what axis this is for you. Remember, start with the North Node, first.
