IMO, some western researchers do not necessarily represent all
western researchers' view. These researchers are probably
wanted to create discord among the disciples on respective
great teachings of both Buddhism and Janism due to their
alaya mind.
Janism is remarkable and is very good a teaching to learn from
both buddhist and western researchers especially its natural
vegetarianism.
Non-violence (Ahimsa) is upheld as the supreme religion and is
practiced in all forms; mental (maan), verbal (vachaan), and
physical (kaya), both knowingly and unknowingly. Jains have a deep
compassion for all forms of life. It believes in equality of souls,
irrespective of differing physical forms, ranging from human beings
to animals and even microscopic living organisms. Jains are
naturally vegetarians
Gotama, while in deep meditation beneath a Bodhi tree, attained
a state of enlightenment that enabled him to comprehend the true
nature of life. This unique achievement eventually led him to be
called the Buddha, which literally means "The Awakened One."
After his Enlightenment, Gotama the Buddha, with his great
compassion and wisdom walked on the dusty paths of India teaching
the Dhamma (teachings) so that those who heard and practiced could
be ennobled and free.
