Srila Prabhupada recommends writing down our realisations for active smaranam

“Realization means you should write, every one of you, what is your realization. What for this Back to Godhead is? You write your realization, what you have realized about Krishna. That is required. It is not passive. Always you should be active. Whenever you find time, you write. Never mind, two lines, four lines, but you write your realization. Sravanam kirtanam, writing or offering prayers, glories. This is one of the function of the Vaisnava. You are hearing, but you have to write also. Then write means smaranam, remembering what you have heard from your spiritual master, from the scripture. Sravanam kirtanam visnoh… about Vishnu, not for others. Don’t write any nonsense thing for any nonsense man. Useless waste of time.

“Vishnu. Write about Vishnu, Krishna. This is cultivation of Krishna consciousness. Hear, write, remember, try to understand. Don’t be dull, dull-headed. Very intelligent. Without being very intelligent, nobody can have full Krishna consciousness. It is for the most intelligent man. So that intelligence will come if you try to understand Krishna. We have got so many books. Always try to understand Krishna. Then you are liberated. Simply by… You cannot understand Krishna in full. He is unlimited; our knowledge is limited. But as far as you can, try to understand Krishna.”
