Hi Asdish: Yes. you can progress rapidly by avoiding dasa akusala and doing meditation.
However, meditation should not be restricted to formal mediation. One needs to be on the lookout for any defiled thoughts that come to the mind at all times. This is real Satipatthana (“sati” + “patthana” or being aware of where the mind is trying to get loose and go off in tangents); see, “Correct Meaning of Vacī Sankhāra“.
