Mahamrityunjaya Mantra

Om Tryambakam Yajamahe
Sugandhim Pushtivardhanam
Urvarukamiva Bandhanan
Mrityor Mukshiya Maamritat

Meaning: We Meditate on the Three-eyed reality
Which permeates and nourishes all like a fragrance. 
May we be liberated from death for the sake of immortality, 
Even as the cucumber is severed from bondage to the creeper.

Feeling something Special

I can't leave nothing for You,But I can leave you for something......
