The horoscopes should always be analysed by Lagna or the Rising sign. Rashi is the sign in which Moon is placed. And moon is only one of the nine planets. Lagna is the fulcrum of the revolving disk of Life and the planets are postioned on this disk while in rotation. If the fulcrum is exactly at the centre, there will be a smooth life and the more it is offset from the centre, the revolution also will not be smooth.
