On the third chapter of book ( 11th ) - from the famous Devi Bhagavata, there are mentioning about Rudrahood.
As per the book " During the time of one's life end time, If he is wearing Rudraksha, And that time his life goes out from the body, He will attain Rudrahood. He does not take birth again on this material world. So anybody who keeps devotion to the lord and wears the rudraksha necklace while dieing he will attain Rudrahood. So One should always wear rudraksha beads"
And to the funny side " We do not have any physical experience on this. Why ? We have to go out of this world to understand what happens after this life :) "
