Rupadhyana is Compulsory
Just as eating food daily is necessary for the body, in the same way, daily meditation is necessary for the soul. Thinking this way, if someone practices religiously for some time - even unwillingly - it will become natural for him to do so. Now such a person will not waste time. People generally are very careless - sleeping eight hours, sleeping ten hours; getting up at 7am on a Sunday! Such actions are not sensible, in spite of being human. If someone starts talking to their wife or children, then they keep talking meaninglessly for hours. People waste their time. Each and every breath of this human life is precious. Even if you do not chant God's names, you must do rupadhyana, i.e. absorbing your mind in loving remembrance on a self-created form of God. His names, qualities and pastimes, etc. are all helpers in this, and that's fine, but the main thing is rupadhyana because it is the mind that has to practice devotion. The root cause of everything is this mind.
Understand that if you do not practice rupadhyana, then your mind will think on the world; it will not sit quietly. Whoever you are thinking about, that is whose devotion it will be considered as. Even if you chant Radhe Radhe with your tongue, but think of your mother, father, wife or son, you will get the fruits of who you meditate on. In other words, you will not get the results of chanting Radhe Radhe. This is why rupadhyana is compulsory.
