In real life it is not possible to delete anyone from memories or feelings

In real life it is not possible to delete anyone from memories or feelings, by pressing any button or even using nuclear radiation or cauterization..

In fact if we consciously try to forget or ignore something or somebody who is bad from our minds the memories cling to us with impossible persistence..

For example when Jaya and Vijaya the doorkeepers of Vaikuntam the abode of Lord Narayana were cursed and ousted from their posts for neglect of duties, they chose the path of expiation by being born as enemies to the Lord in the shape of Hinranyaksha, Hiranyakashipu, Ravana and Kumbhakarna and Shishupala and Dantavaktra..

Their theory was that when one hated the Lord as enemy His thoughts would be present in their minds all their time.. and each of them got killed by the Lord thrice and returned to Vaikuntam to resume their charges..

Had they chosen the path of pious persons for expiation, they would have been forced to spend many more Yugas to return to their Master...
