Remembrance of Krishna is not possible for the impure soul who has not practiced Krishna consciousness in devotional service. Therefore, one should practice Krishna consciousness from the very beginning of life. If one wants to achieve success at the end of his life, the process of remembering Krishna is essential. Therefore, one should constantly and incessantly chant the Hare Krishna Maha Mantra.
Life should be moulded in such a way so that we can be able to remember the Lord constantly.
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.
