Aikido ~ (合気道 Aikidō, also 合氣道 using an older style of kanji) Literally meaning “harmony energy way”, or with some poetic license, “way of the harmonious spirit”, is a gendai budo – a modern Japanese martial art. Practitioners of aikido are known as aikidoka. It was developed by Morihei Ueshiba (植芝盛平) (also known by aikidoka as o-sensei (大先生)) over the period of the 1930s to the 1960s. Technically, the major parts of aikido are derived from Daitō-ryū Aiki-jūjutsu (大東流合気柔術), a form of jujutsu with many joint techniques, and kenjutsu (剣術), or Japanese sword technique (some believe the tactics in Aikido are especially influenced by Yagyū Shinkage-ryū). Aikido is also considered to contain a significant spiritual component.
Materialism is the theory that the only thing that exists is matter or energy; that all things are composed of material and all phenomena (including consciousness) are the result of material interactions. In other words, matter is the only substance, and reality is identical with the actually occurring states of energy and matter. To many philosophers, materialism is synonymous with physicalism. However, materialists have historically held that everything is made of matter, but physics has shown that gravity, for example, is not made of matter in the traditional sense so physicalism is used to emphasize a connection to physics and the physical sciences.
Parigraha is the concept of possessiveness and greed. It also refers to the desire for and attachment to material things. The word comes from the Sanskrit, pari, meaning “on all sides,” and graha, meaning “to grab.” Therefore, the term may be translated as “taking more than one needs.”
In yoga, parigraha is the opposite of aparigrapha (non-possessiveness). Striving for aparigraha, or eliminating parigraha, is one of the yamas (restraints) that the sage, Patanjali, lists in his Yoga Sutras.
