Why is it inauspicious to shake legs while sitting, if you know the reason then you will never do it again

Shaking legs while sitting or lying down is not only a wrong habit but it has a deep connection with astrology. According to the scriptures, moving the legs while sitting on cot, chair, bed etc. at high places or lying down makes the Moon weak in the horoscope. In such a situation, a person has to go through mental stress due to the inauspicious effects of the moon.
