Generally human beings and animals dont remember their past lives,
so 1. why is that? and
If we dont remember anything in the next life, why strive for enlightenment at all? Isnt it true that I wont remember anything of my temporary life in my next life?
Do for example beings in the hell or heavenly realms remember their past life? Why would a person be afraid of being reborn in the hell realm if said person wouldnt even remember his/her past life?
Are there tulkus/rinpoches etc. who are known to remember their past life(s)?
