The philosopher's stone

   The philosopher's stone is a legendary substance, allegedly capable of turning inexpensive metals into gold. It was sometimes believed to be an elixir of life, useful for rejuvenation and possibly for achieving immortality. For a long time, it was the most sought-after goal in Western alchemy ,meditated upon by alchemists like Sir Isaac Newton, Nicolas Flamel, and Frater Albertus.In the view of spiritual alchemy, making the philosopher's stone would bring enlightenment upon the maker and conclude the Great Work. It is also known by several other names, such as 'materia prima.'

     The origins of the philosopher's stone seem to be in ancient Hinduism.A great Hindu sage wrote about the spiritual accomplishment of Gnosis using the metaphor of the philosopher's stone. Saint Jnaneshwar (1275-1296), wrote a commentary with 17 references to the philosopher's stone that explicitly transmutes base metal into gold. The seventh century Indian sage Thirumoolar in his classic Tirumandhiram explains man's path to immortal divinity. In verse 2709 he declares that the name of God, Shiva or the god Shambala, is an alchemical vehicle that turns the body into immortal gold. His poetry resonates with the deathless nature of spiritual attainment. And since God Shiva is usually depicted through a Shivalinga, a sculpted stone, this is possibly the origin.

    The 8th-century Persian alchemist Jābir ibn Hayyān (latinized as Geber) analyzed each classical element in terms of the four basic qualities of hotness, coldness, dryness, and moistness. Fire was both hot and dry, earth cold and dry, water cold and moist, and air hot and moist. He further theorized that every metal was a combination of these four principles, two of them interior and two exterior. From this premise, it was reasoned that the transmutation of one metal into another could be affected by the rearrangement of its basic qualities. This change would presumably be mediated by a substance, which came to be called al-iksir in Arabic (from which the Western term elixir is derived).

   Although the alchemists went to great pains to conceal the true order of the steps of the formula for making the Stone, the correct order according to the Emerald Tablet is: 

• Calcination, 
• Dissolution, 
• Separation, 
• Conjunction, 
• Fermentation, 
• Distillation, 
• Coagulation.

  
  The mystical revival in the late 20th century renovated the public interest on alchemy, and particularly on this metaphysical and philosophical conception of the philosopher's stone - which is now subscribed by many people, especially within several New Age movements
