'm still getting frustrated about this STS / STO thing... I wish there was an easy explanation, because it's such a core concept for cassiopaea and similar material. At some level every action is STO (if you look at it from 6D perspective), even though it might seem STS on these lower levels...
Probably everyone in this forum has asked themselves the same questions about what it means to be SAS and SAD, and especially how to apply it in their daily lives.
I believe that simply seeking answers is part of the right path for a SAD candidate. You don't need to have all the answers at the beginning. Here in the forum, there are many clues, but the path is one of self-knowledge, step by step.
The more we know ourselves, the more we can purify our intention, as it is said in Sufism. But we often hide our true intentions under a cloak of kindness and service to others, but when we are honest with ourselves, we can see that ultimately there can be a goal of service to oneself.
Seeing this contradiction is already a step forward.
Regarding the step-by-step process, the Sufi teachings that indicate that the "self" or "nafs" is divided into seven levels or stages can be helpful. The first three are:
1. The Inciting Self, or Lower Self, or the Tyrant Self: At this stage, the self is dominated by worldly passions and desires, driving the person toward evil and lust.
2. The Self-Reproaching Self: At this level, the self begins to become aware of its mistakes and reproaches itself for its actions. I believe your questions arise from this state of self, in which self-knowledge begins, the search for a moral compass (which is being STO and STO), and the constant struggle to align our actions with that compass.
3. The Inspired Self: The self receives divine inspiration and begins to realize its spiritual potential, seeking truth and divine guidance. I believe at this level we are able to integrate the knowledge we have received. In my country, they say "Me cayó la teja". I believe in English, it's "The penny dropped" or "It finally clicked."
Obviously, these states aren't a continuous, direct, upward path. I'd say it's a roller coaster, or at best, a spiral.
In short, what I'm trying to say is that there have been times when I've felt hopeless and confused about these concepts and how to apply them to my life.
In those moments, trusting the process has helped me. That has allowed me to enjoy the journey. Praying, meditating, and grounding myself in the present has also been very helpful when I'm feeling mentally confused and anxious.
I hope this helps.
