first time - year 2000 when I was 17 years old.
Neptune was transiting my natal Moon and it was a time of deep spiritual happenings for me.
The story how it actually started is the most interesting and now I strongly believe this was not a random thing, I still remember that day.
I accidentally(?) stumbled upon an astrology site(I think now it was astro.com), entered my birth data and got my chart drawing there. Before this, I only knew my sun sign and ascendant, so this chart graphics meant nothing to me, glyphs of signs and planets, and also aspects had no meaning. I knew the popular Moon, Venus and Mars glyphs. I find it strange now how stubborn I was to find out what it all meant.
I stared at my chart for hours and it kind of started to make sense. I noticed that the same distance between planets was marked the same, how every fourth sign had the same coloring, assumed A, F, E, W stood for elements, I noticed red lines and blue lines, and soon started reading about explanation of this all.
I became very obsessed with astrology after this, even tho I knew not so much about it, so I kind of distanced myself from it from 2002-2007. I felt I was going nowhere, had the urge to see it all and know it all, but astrology seemed so huge and complex(still is), except now I approached it more patiently, I am relaxed about it, in no rush to get anywhere or to get answers, I simply feel it nicely compliments some spiritual knowlegde I have about this world.
