A method, system and bit steering assembly for directional drilling of a borehole in a formation is presented. The method includes the steps of: providing a drill string having a central fluid passage extending along a longitudinal axis of the drill string for passing drilling fluid to the drill bit. The drill bit has a plurality of nozzles for expelling the drilling fluid, wherein each nozzle is arranged eccentrically with respect to the longitudinal axis. The method includes introducing a bit steering assembly, rotating the drill string, and pumping drilling fluid through the central fluid passage. The drilling fluid activates a first impeller of a first rotor section to rotate in a first direction, and activates a second impeller of a second rotor section to rotate in a second direction opposite the first direction. The method includes adjusting a coupling between the first rotor section and the second rotor section.
