Pranayama is the fourth limb of the eight limbs of Ashtanga Yoga mentioned in verse 2.29 in the Yoga Sutras of Patanjali. Patanjali, a Hindu Rishi, discusses his specific approach to pranayama in verses 2.49 through 2.51, and devotes verses 2.52 and 2.53 to explaining the benefits of the practice.
The Communist Manifesto was first published in February 1848 in London. It was written by Marx and Engels for the Communist League, an organisation of German emigre workers living in several western European countries.
While the late twentieth century saw the Soviet Union crumble, leaving capitalism seemingly the victor, the socialist plan sparked by The Communist Manifesto nevertheless remains a strong influence on the world's political and philosophical thought, and The Communist Manifesto itself is assured an eminent place in the history of human experience, both for the revolutionary philosophy it presents and for the way it changed the face of nation-building.
