Jews keep borrowing from various cultures or sources to reinvent their beliefs, attitudes and practices.<quoted text>
Judaism, on the other hand, has always embraced intellectual inquiry and debate, so modernism has never been a real threat to the practice of the religion.
If a faith is based on cosmic principles then it need not reinvent itself nor does it need to readjust its values since the cosmic principles on which it stands are eternal.
Vedanta and Buddhism are faiths based on cosmic principles as seen in their expositions and so these faiths need not adjust themselves with the march of time. Who can dispute the laws of consciousness, space, singularity, space, time and the rest? These are the cosmic principles that never change.
