Yes Uma,
I know it is written in Gita.
vasamsi jirnani yatha vihaya
navani grhnati naro 'parani
tatha sarirani vihaya jirnany
anyani samyati navani deh
TRANSLATION
As a person puts on new garments, giving up old ones, similarly, the soul accepts new material bodies, giving up the old and useless ones.
Arjuna is advised herewith by the Lord not to lament for the bodily change of his old grandfather and his teacher. He should rather be happy to kill their bodies in the righteous fight so that they may be cleansed at once of all reactions from various bodily activities. One who lays down his life on the sacrificial altar, or in the proper battlefield, is at once cleansed of bodily reactions and promoted to a higher status of life. So there was no cause for Arjuna's lamentation.
-------------------
Means what is important is soul not body. Soul only uses for own purposes.
It is also written in Gita that soul always remains new while body becomes old and in the end turns into ashes.
-----------------------
My point is only that one learns this mostly by experience , life is a good teacher. It can not be drilled into someone by outer means.
Though it is also true that few who are more inclined towards spiritualism from young age may learn it through ' Guru' or books.
-----------------------
In Gita Krishna said to Arjun ...
Some come to the spiritual life because of suffering, some in order to understand life; some come through a desire to achieve life's purpose, and some come who are men and women of wisdom. Unwavering in devotion, always united with me, the man or woman of wisdom surpasses all the others.
