because that corresponds to the same point in the sky as vedic 11 degree taurus .labelling that point in the sky differently does not change the transit effect to that portion of the heavens.it is still alligned with the star prima hyadum in the constellation of taurus and quite close to aldeberan the eye of the bull in taurus.so when you were born prima hyadum was rising and aldeberan was about to rise aspects to this point would effect you personally .regardless of the labelling.
Mulaian i understand what you are saying here. The only thing that would be different is the labeling. The aspects to the planets and points on the chart would be the same just the interpretaions of the signs that occupy these areas would be different. Right?
