There must be cleansing and purifying of all the senses and five inner implements mind, intellect, chitta, prana and ego in the path of sadhana. It is not that you cannot start the sadhana before cleansing. One can definitely start with Naam-Smaran, prayers, meditation etc., Naam-Smaran needs to be done with the Bhavna-Dharana of the heart while performing all worldly activities. Smaran-Bhavna of Shree Bhagwan is maintained with this sadhana. Bhavna of Shree Bhagwan should be maintained in all works and the Bhavna that all the work is done for the development of life should be present in our hearts with that kind of Chetana - awareness. Work should be started with heartfelt Bhava of prayer and work is continued for the love of Shree Prabhu and in the end it is offered to Him with love, devotion, and knowledge. In this way all the thoughts, vrutties etc., are offered to Him. We need to manifest Samata by our understanding that we are separate from all the activities of the senses and inner implements like mind etc., during the activities at that time. We must deny all the negative that spring up, as if we have nothing to do with it. If something constructive spring up, we should do it with non-attachment and with the Bhava that we are separate from it. The main characteristic, whether purification is going on or not is that we experience the establishment of peace, Samata, patience etc., in our senses and inner implements like mind, intellect etc.
