There are many people who do not consider Buddhism a religion,
partly because Buddhists does not worship anyone, let alone any
idols or images. We do not worship deities, gods, spirits, God, or
Buddha. Even the Buddha did not claim to be god, neither do we
treat him as god, but the wisest teacher who relieves our
sufferings of samsara, gives us insight on life, give us the dharma
that leads to bliss and joyfulness, and Wisdom.
There are Buddhist figures that appear in other religions, the most
commonly known one is Guan Yin. Guan Yin is commonly worshipped by
the Taoists. However there is a lot of difference between Taoism
nowadays and Buddhism. Guan Yin, along with other deities like the
Jade Emperor. The Jade Emperor in Taoism actually derives from
Buddhism, one heavenly king we call Lord Sakra. As the Lord Sakra
is not yet enlightened, we do not take refuge in him, neither do we
worship him, but we pay reverence and repsect to the heavenly deity
also. Other characters like Ji Gong, is also from Buddhism. However
it is protrayed very differently from what it really was. Ji Gong
was an enlightened saint [an Arhant]. He is being freed from
Samsara and enters Nirvana after his death. He is is no longer
trapped in the rebirth cycle of Samsara. However very unfortunately
some people worships Ji Gong as a form of spirit-deity. This is a
very deluded view. The spirit/ghost realm is one of the 3 lower
realms, the Arhant who is free from samsara, how could he possibly
be reborn in the lower realm?
We take refuge in the Triple Jems, which are: Buddha, Buddhadharma
[truths & teachings], and the Sangha [community of monks]. In
Buddhism, Guan Shir Yin Pu Sa [Avalokitesvara Bodhisattva] is a
role model of the Mahabodhisattva [Da Pu Sa], someone whom we
should learn from, one who seeks liberation himself and also helps
liberate the other sentient beings out of great compassion.
We revere our world honoured one, Buddha Shakyamuni, and other
Buddhist Bodhisattvas and Saints (Arhants) whom set an example for
us on the path towards Enlightenment. We bow to them in reverence
respect, also a practise of eliminating the "Ego-Form", but we do
not really worship them like in other religions. Definitely
Buddhists do not engage in Idol-Worshipping, which is clearly
stated in the Diamond Sutra:
"If one sees me in forms,
If one seeks me in sounds,
He practices a deviant way,
And cannot see the Tathagata." - Buddha
In fact forms and statues of Buddhas are a later development of
Buddhism and did not appear at the very beginning.
