Can we become immortal ?

Many psychologists and scientists have been doing research on what happens to the soul once the time had come for soul to leave the body. Some have been engaged also in past life regression.We in India, have known this subject from ancient times.  I was listening to a talk by one of our Sisters on the subject of DEATH, who said, death is an  inevitable event whether in Satyug or in Kaliyug. The difference lies only in the attitude of the people.  In Satyug , people being more knowledgeable and wise did not harbor any anxiety about death and so people generally have been saying Satyug people were immortal. The people in Satyug did not suffer even during transition. For them it was as easy as changing clothes. In contrast, in Kaliyug we may have all the theoretically acquired knowledge of the process and yet we suffer, because of our attachments to number of things, including our body, which we know is worn out and requires replacement. The solution offered by the Sister was, we must build a strong relation with our Parampita, so that the transition becomes easy.  Stronger the bond with Paramatma,  less the suffering. It is then that one can ensure the  great feeling of  IMMORTALITY  which our ancestors in Satyug must have enjoyed.
