pase anfas and other such methods are only tools to constantly remember Allah,actual ziker is to keep away from sin and adhere to sunna and sharia.unfortunately most of us take these tools as a purpose in themself,Pase anfas without adherence to sharia will not help any one in akhera.Tassawuf is an art of tazkia e nafse,all the rest are acceseries,and not a part of the actual art.Ignoring this basic fact has ,unfortunately,given an altogether different shape to this noble tariqa.
