Transformation isn't always about changing to something new, something different. It can be about peeling off layers of excess baggage and gradually going back to the original self.
It may feel strange and new at first, because we are used the false self more than our true, long forgotten essence, but depending on the force that is actually influencing you to change, you are in fact, just deconstructing false and synthetic parts of yourself.
Ketu (or commonly known in western astrology as "South Node") is our root, our essence, which is why it's related to the past. I'm under it's dasha (period of time) right now and it's truly amazing the ways in which it pressures you to go back to your most raw, authentic self. Which can be disturbing when we're too attached to those false ideas we have of ourselves and our reality.
It can strip you in a way that will either bring you sorrow, or peace. It can also cause a lot of confusion, because as it strips away the false layers, you start to feel disoriented mentally, because you simply don't know who you are anymore.
You start to detach from your egoic self, and although most people think that is a positive thing, the ego actually grounds us here so without it, we can be feel extremely discombobulated.
At the end, this is an opportunity to see what is real and what isn't. If we accept the cleanse and follow it's flow, we are left with authentic and original beauty. The act of frantic self stimulation is a perfect mirror of forced manifestation.
The individual strokes their own tool of creative power, while forcing their mind to imagine provocative imagery, in attempt to stimulate pleasurable sensations. Although the frantic movements are more interested in the final discharge and climax.
The act of rational based and forced creation of reality is exactly the same.
You compulsively imagine what you desire (a provocative imagery that triggers satisfaction in your nervous system), and "energetically stroke" your creative channels in order to reach the final materialization of your desire.
The truth is, when you stop utilizing your mind to force the process and connect with your body, the amount of satisfaction you experience is far beyond what the mind can offer.
When you do that (literally for self pleasure or manifestation) you don't leave yourself sore, exhausted and drained.
Venus is related to the nectar of life, the sexual discharge and is why Venus individuals are always agitated internally to create/discharge, due to them having an abundant reservoir of "juice".
