I heard Prabhupada chanting Hare Krishna at the end moment.
Shravanam, Kirtanam, Smaranam. Kirtaniya sada hari. Constantly remember. So, at the time of death, we will be able to glorify the Lord.
By glorifying the Lord, we can remain in His association.
The only purpose is to remember the Lord at the end of life. Only one purpose, “ante narayana smriti”.
