If your car is moving, don’t forget whose push started it to get it going. Similarly, always remember the different gurus that got you moving on the path of devotion.
Either pure or impure, or having passed through all conditions of material life, if one can remember the lotus eyed Krishna, he becomes externally and internally clean.
Remembrance and Prayers also can give us the desired result if they are properly done under expert guidance.
When anarthas will be removed due to chanting the Holy Name, then Krishna‘s form, qualities and pastimes will automatically manifest from the name. There is no need to make an endeavor to artificially remember His form, qualities and pastimes.
Always remember Krishna who is your dear most friend and always serve Him just to please Him and He will give you all intelligence how to be a first class devotee.
Remembrance is a necessary expression of love, internally.
