meaning of om namah sivaya
The meaning of the Namaḥ Śivāya mantra was explained by Satguru Sivaya Subramuniyaswami:
Na is the Lord's concealing grace, Ma is the world, Śi stands for Śiva, Va is His revealing grace, Ya is the soul. The five elements, too, are embodied in this ancient formula for invocation. Na is earth, Ma is water, Śi is fire, Vā is air, and Ya is ether, or Ākāśa. Many are its meanings.
Namaḥ Śivāya quells the instinct, cuts through the steel bands and turns this intellect within and on itself, to face itself and see its ignorance.
The book "The Ancient Power of Sanskrit Mantra and Ceremony: Volume I" by Thomas Ashley-Farrand defines Om Namah Shivaya as:
"This mantra has no direct translation. The sounds relate directly to the principles which govern each of the first five chakras on the spine...Earth, water, fire, air, ether. Notice that this does not refer to the chakras themselves which have a different set of seed sounds, but rather, the principles which govern those chakras in their place. A very rough, non-literal translation could be something like, 'Om and salutations to that which I am capable of becoming.' This mantra will start one out on the path of subtle development of spiritual attainments. It is the beginning on the path of Siddha Yoga, or the Yoga of Perfection of the Divine Vehicle."
"Na" refers to the Gross Body (annamayakosa), "Ma" refers to the Pranic Body (pranamayakosa), "Shi" or "Chi" refers to the Mental Body (manonmayakosa), "Va" refers to the Intellectual Body (vignanamayakosa) and "Ya" refers to the Blissful Body (anandamayakosa) and "OM" or the "silence" beyond these syllables refers to the Soul or Life within.
Maha Shivaratri
It literally means the great night of Shiva or the night of Shiva. It is celebrated every year on the 13th night/14th day of the Maagha or Phalguna month of Hindu calendar.
According to the Shiva Purana, the Mahashivaratri worship must incorporate six items:
Bathing the Shiv Linga with water, milk and honey, and Wood apple or bel leaves added to it, representing purification of the soul;
The vermilion paste applied on the Shiv linga after bathing it, representing virtue;
Offering of fruits, which is conducive to longevity and gratification of desires;
Burning incense, yielding wealth;
The lighting of the lamp which is conducive to the attainment of knowledge;
And betel leaves marking satisfaction with worldly pleasures.
Tripundra refers to the three horizontal stripes of holy ash applied to the forehead by worshippers of Lord Shiva. These stripes symbolise spiritual knowledge, purity and penance (spiritual practice of Yoga), so also they represent the three eyes of Lord Shiva.
