This is a harsh but necessary Lal Kitab warning from Dr. Sharma regarding the dark side of Rahu in the 7th house.
Because Rahu in the 7th causes constant financial drain (as explained in the previous post), the person often becomes desperate for money. This desperation leads to moral corruption.
Dr. Sharma warns that if this Rahu is afflicted, the person will almost certainly betray their business or life partner ("partner ko dhokha dega"). Furthermore, if they are in a position of power, they will be highly tempted to take bribes or engage in corrupt financial practices ("rishwat lega hi lega"). Strict moral discipline is the only remedy.
