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.
Vladimir Lenin founded the Russian Communist Party, led the Bolshevik Revolution and was the architect of the Soviet state. He was the posthumous source of Leninism, the doctrine codified and conjoined with Marx's works by Leninâs successors to form Marxism-Leninism, which became the Communist worldview.
