A person who follows blindly without finding out the truth sees
Buddhism as mysterious. The person who researched into Buddhism may
find it complex. However the one who practices find Buddhism in
fact, very simple.
There's an important point which Ven.Dhammananda pointed out:
Practice is important in
Buddhism. A person who studies much but does not practise is like
one who is able to recite recipes from a huge cooker-book without
trying to prepare a single dish. His hunger cannot be relieved by
book knowledge alone. Practice is such an important prerequisite of
enlightenment that in some schools of Buddhism, such as Zen,
practice is put even ahead of knowledge.
Viewing Budhism as simply a religion, or simply philosophy, are
IMHO, not complete.
Ven. Jue-Hsing
A scholar once asked, "Buddhism seems a great theory, and I find it
useful. Is Buddhism a Philosophy?"
"Master Shen-Kai once said 'Buddhism is not Philosophy but beyond
Philosophy,'" I replied.
"Why so?" The scholar asked.
"Philosophy is a system of thoughts based upon logical reasoning."
I answered. "However, Buddhism is about realizing truths while
detaching from thoughts."
