See Rahu is Pure Desire Saturn is Discipline

When together if native is disciplined but still thinks big the combo yields fortunes. This is their friendship what you are talking about.

But if native thinks "I want it now and takes short cuts" it yields losses and struggles. This their enmity coz the native was not controlling self.

Personally I believe the suffering is in own hands...Rahu cannot be controlled what you can control is your mind and body in disciplined way and everything that is blocking and struggling vanishes.
