Hinduism is rich in symbolism. Many acts of worship, such as puja, are symbolic, a form of visualisation in which worshippers simulate activities normally performed on higher planes of existence. Thus the scope of symbolism is broad and includes physical acts such as offering pranam (obeisances) with folded hands. Such physical gestures tend to induce the appropriate mood and awareness within the practitioner. Many symbols are considered auspicious, embodying the notion of inner purity. Sacred emblems are displayed in the home or temple to invoke good fortune. The most popular symbols are listed on the right.
Aum,
also written "Om" and called pranava, is the most important Hindu symbol.
Its prolonged intonation is associated with the primeval sound through which
the universe was created. It is thought to contain all things. It consists
of three syllables — a-u-m — which are sounded progressively from the throat
to the lips. The three sounds are considered to symbolise many items, but
perhaps most importantly the three states of consciousness – waking, dreaming,
and deep sleep. The entire symbol represents the fourth state, which is the
awareness of one's own spiritual identity. Aum is the most important mula (root) mantra and is thus chanted at the beginning of many prayers, mantras, and rituals.
Hindu people greet each other by placing their two hands together and slightly bowing the head, whilst saying namaste or a similar phrase. They adopt the same posture when greeting the temple deity or a holy person. Thus when greeting another person, a Hindu is offering respect to the soul within (atman) and also to God within the heart (Paramatman).
Many Hindus consider that religious symbols embody the divine, and are in themselves sacred. Hence the symbolic murti (sacred image) or prasada (sanctified food) not only point to transcendence but become that transcendence (Brahman) if invoked with love and devotion (see also Bhagavad-gita 4.24).
