Nammalvar also Nammazhwar,Nammaazhvaar, Nammazhvar, Nammaalvaar, Nammalwar;Tamil: நம்மாழ்வார்) was one of the twelve Alvars, well known for his many hymns on devotion to Vishnu. Legend gives him the date 3102 B.C. (i.e., the beginning of the kali yuga). He was born in the asterism Visakham, in what is now thirupathi saaram (also known as Thiruvenparisaaram), Tamil Nadu. His name means "our own alvar (alvar means "one immersed in God"). He was also known as Maran and Satakopan.

He was born in a small town called Thiruvenparisaaram, in the southernmost region of the Tamil country — nagercoil. His father, Kari, was a petty prince who paid tribute to the Pandyan King of Madurai. He must have been born fully enlightened because as a baby he never cried or suckled and never opened his eyes. According to legend, as a child he responded to no external stimuli and his parents left him at the feet of the deity of Lord Sri Adhinathar in Alwarthirunagari. The child then got up and climbed into a hole in a tamarind, sat in the lotus position, and began to meditate. It appears he was in this state for as long as sixteen years when a Tamil poet and scholar in North India named Madhurakavi Alvar saw a bright light shining to the south, and followed it until he reached Nammalvar's tree. Unable to elicit any reaction from the child, he asked him a riddle: "If the small is born in a dead's body(or stomach), what will it eat and where will it stay?" meaning, if the subtle soul is embodied in the gross body, what are its actions and thoughts? Nammalvar broke his lifelong silence and responded, "That it will eat, and there it will rest!" meaning that if the soul identifies with the body, it will be the body but if it serves the divine, it will stay in vaikunta and eat(think) of God. Madhurakavi Alvar realized the divinity of this child.

Natural farming is an ecological farming approach established by Masanobu Fukuoka (1913–2008), a Japanese farmer and philosopher who described his agricultural philosophy as shizen nōhō (自然農法^?) in Japanese. It is also referred to as "the Fukuoka Method", "the natural way of farming" or "do-nothing farming". The title refers not to lack of labor, but to the avoidance of manufactured inputs and equipment. Natural farming can also be described as ecological farming and is related to organic farming, sustainable agriculture, agroforestry, ecoagriculture and permaculture but should be distinguished from biodynamic agriculture.

The system exploits the complexity of living organisms that shape each particular ecosystem. Fukuoka saw farming not just as a means of producing food but as an aesthetic or spiritual approach to life, the ultimate goal of which was, "the cultivation and perfection of human beings". He suggested that farmers could benefit from closely observing local conditions. Natural farming is a closed system, one that demands no inputs and mimics nature.
