It was two years back when I was
about to wear a tattoo and that too in the form of trident as being a Hindu
mythology aficionado, I came across cool significances of the Trishul.
Trishul has great connotation in
Hindu Religion, it is in the hands of almost all the deities, but the significance
is even more when it is held by Lord Shiva. Now why Trishul has been given so
much of significance in our culture does have a very deep meaning which is
beyond the apparent.
Trishul is polyvalent and rich in
nature. Polyvalent means having the
property of counteracting several related poisons or giving immunity against
many different strains of a microorganism. But in our case it has the capacity
to remove our many different negative qualities which inhibit us to be one with
the almighty so helps to makes us rich at spiritual level. Ignore the spiritual
level enrichment and all. This is the symbol of positivity. Sounds good.. 

The three prongs of Trishul
represents —
- Trinity -brahma , Vishnu , Mahesh ;sarasvati , lakshami and kaali
- 3 -modes of nature --creation, maintenance and destruction
- The 3 -kaala -past, present and future
- The 3 -Gunas -sat, raj, tam
- 3 -lokas -swarg , bhu and patal
- 3 -powers -will , action and wisdom
- 3 -types of miseries -physical, mental and spiritual
Lord Shiva’s Trishul is supposed
to destroy -the physical world -attachment to gross the illusionary world
which seems so real; the world of the mind -the Ahamkaar or ego which is a
barrier between Me and HIM -thus transforms to be in the third world that is
the world of spirituality -thus leads to oneness Shiva into a single non-dual
plane of existence, that is bliss alone.
SHIVA HOLDS THE HANDLE means Lord is BEYOND ALL THE TRIGUNAAS means HE is NIRGUN(really??..

Yogic symbolism:
The trishula also represents the
nadis or energy currents within the subtle body. The ida (feminine, passive)
and the pingala (male, active) channels spiral upwards like a double helix,
crossing for the last time at the Vishuddha or throat chakra. These are normally represented as snakes. The
central channels or sushumna nadi goes straight up the spine, continuing up
through the crown chakra where the other two channels terminate. The channels
in this area form a trishula-like shape.
