Yoga meaning union in Sanskrit is a family of ancient spiritual practices that originated in India, where it remains a vibrant living tradition and is seen as a means to enlightenment. Karma Yoga, Bhakti Yoga, Jnana Yoga, and Raja Yoga are considered the four main yogas, but there are many other types. In other parts of the world where yoga is popular, notably the West, Yoga has become associated with the asanas of Hatha Yoga, which are popularly considered there as fitness exercises and also form the basis of an expanding business.Yoga as a means to enlightenment is central to Hinduism, Buddhism, Jainism and has influenced other religious and spiritual practices throughout the world. Ancient Hindu texts establishing the basis for yoga include the Upanishads, Yoga Sutras of Patanjali, the Bhagavad Gita, the Hatha Yoga Pradipika and many others, which specify the criteria of having successfully mastered a particular yoga technique.

Erosion is the displacement of solids by the agents of wind, water or ice, by downward or down-slope movement in response to gravity or by living organisms . Erosion is distinguished from weathering, which is the decomposition of rock and particles through processes where no movement is involved, although the two processes may be concurrent.
Erosion is an intrinsic natural process but in many places it is increased by human land use. Poor land use practices include deforestation, overgrazing, unmanaged construction activity and road or trail building. wever, improved land use practices can limit erosion, using techniques like terrace-building and tree planting.A certain amount of erosion is natural and, in fact, healthy for the ecosystem. For example, gravels continually move downstream in watercourses. Excessive erosion, however, can cause problems, such as receiving water sedimentation, ecosystem damage and outright loss of soil.

Structural failure refers to loss of the load-carrying capacity of a component or member within the structure or of the structure itself. Structural failure is initiated when the material is stressed to its strength limit, thus causing fracture or excessive deformations. The ultimate failure strength of the material, component or system is its maximum load-bearing capacity. When this limit is reached, damage to the material has been done, and its load-bearing capacity is reduced significantly and quickly. In a well-designed system, a localized failure should not cause immediate or even progressive collapse of the entire structure. Ultimate failure strength is one of the limit states that must be accounted for in civil engineering.
