Shiva means Kalyan (blessed happiness for all). There is no word parallel to it in world dictionary. Hindus want happiness for all. That is why they recite “Om Namah Shivaya” – I humbly surrender to the Supreme who blesses all with happiness. No other philosophy in world apart from Hinduism is rooted in seeking well-being for all without discrimination.

Shivalinga means something that can be symbolized as Shiva (something on which we can associate our emotions of seeking blessed happiness for all.) Shivalinga is nothing but representation of that cosmic pillar on which we can concentrate (like on flame) and attribute our Shiva-emotions. That is why it is also called Jyotirlinga. Jyoti – light that takes away the darkness inside you. The path of enlightenment that leads to divine brilliance. (Adityavarnam Tamasah Parastaat – Full of light, not darkness whatsoever). It works phenomenally well. It has worked wonders who followed this approach to Yog Siddhi. That is why Shiva is called Source of all Yog Siddhis.

The whole Shiva-Upasana fills mind with Bhakti, activates dormant aspects of personality, super-charges you and ensures you are in right path.
