6.15.7

देहेन देहिनो राजन् देहाद्देहोऽभिजायते । बीजादेव यथा बीजं देह्यर्थ इव शाश्वत: ॥ ७ ॥

dehena dehino rajan dehad deho ’bhijayate bijad eva yatha bijam dehy artha iva sasvatah

dehena
by the body
dehinah
of the father possessing a material body
rajan
O King
dehat
from the body (of the mother)
dehah
another body
abhijayate
takes birth
bijat
from one seed
eva
indeed
yatha
just as
bijam
another seed
dehi
a person who has accepted a material body
arthah
the material elements
iva
like
sasvatah
eternal.

As from one seed another seed is generated, O King, so from one body (the body of the father), through another body (the body of the mother), a third body is generated (the body of a son). As the elements of the material body are eternal, the living entity who appears through these material elements is also eternal.
