Budhhist's Philosophy of re-birth

Buddhist think and preach differently their concept of re-birth.It need to be evaluate consciously at one hand their literature advocates ...

“I find it helpful to compare the cycles of life and death to the daily rhythms of waking and sleeping. Just as we look forward to the rest sleep brings after the efforts and exertions of the day, death can be seen as a welcome period of rest and re-energizing in preparation for a new round of active life. And just as we enjoy the best sleep after a day in which we have done our very best, a calm and easy death can only follow a life lived to the fullest without any regrets.”
Wisdom for Modern Life by Daisaku Ikeda.
and
“According to the Bodhisattva rule, Masters of Khamtrul Rinpoche’s caliber are not meant to stay away for long, however. Consequently immediately after his cremation his disciples began to look for clues as to where his future might be found.....Finally the [eminent Lama] Karmapa gave the name of the place where Khamtrul Rinpoche had been reborn - Bomdila, a Himalayan town close to Bhutan...the discovery of the ninth Khamtrul Rinpoche was in the bag. The child was found, recognised and reinstated in Tashi Jong to take up his spiritual duties where his predecessor - himself - had left off”.
and still another ...
“ Enlightenment was plodding and exceedingly hard work. The Lamas said if you reached there in three lifetimes you were moving incredibly quickly...” page 115


But at the same time we find out
”Buddhism does not accept the immortality of soul or the idea that the body is a vessel for the soul, and after death, the soul departs from the body, and moves to another body”.
(Ikeda/Tehranian:Global Civilisation, p.120).

From all this what we get conclusion is ...
“There is no fixed self that lives on as an unchanging entity”
(Unlocking the Mysteries of Birth and Death p 26).
In contrast to the idea of “continuity of person” after death, Buddhism teaches “continuity of life” after death. All phenomena, stars, galaxies, plants, animals, people..etc... undergo the eternal cycle of birth and death. Rebirth in a future existence is not a continuity of a past personality or past social status - but a new fresh start.

Conclusion

What ursula rightly said in above comment,Buddhist's Belief of re-birth is some what alike advanced religion,which believe a person start a mission good or bad doesnt destroy or simply vanish away by his death,but the nature the energy empowering the life continues it,it gets a re-birth in a new formed leader who regardless of same gender,class,creed or physical appearance necessarily possess all the traits,trends and tendencies advocating the same karmic seed of the leader whom he/she replacing.
