and one born at the two twilights may put his own life at risk. There is no reversal in gandanta (the edge-point between signs). A son or a daughter born in Moola may put the father-in-law's life at risk.
Simple meaning: A twilight birth may risk the child's own life. A Moola birth may risk the father-in-law's life.
तदंत्यपादजो नैव तथाश्लेषाद्यपादजः ।
A boy born in Jyeshtha's last quarter may put an elder sibling at risk. Mula's last quarter does not.
आरभ्योद्वाहदिवसात् षष्ठे वाप्यष्टमे दिने ।
The bride enters the new home on the 6th, 8th, 10th or 7th day after the wedding.
हायनद्वितयं जन्मभलग्नदिवसानपि ।
Skip two years and the birth star and lagna days. The wedding journey is then good, even with Venus set.
