He wrote the book in Gujarati under the title Satya Na Prayogo, publishing it in parts in his journal, and Mahadev Desai translated it into English.

During a long famine in Magadha, Bhadrabahu led a body of monks south to Shravanabelagola in Karnataka while Sthulabhadra stayed in the north and convened a council at Pataliputra.

Because early sculptors at Sanchi and Bharhut did not show the Buddha in human form, they used signs, and the wheel stands for the first sermon at Sarnath, which is itself called the turning of the wheel of law.

He presided over the First Buddhist Council, held at Rajgriha soon after the Mahaparinirvana in the reign of Ajatashatru, whose purpose was to settle the teaching before it could be distorted.

Mahavira preached in the spoken tongue of Magadha, and the twelve Angas that preserve his teaching are in Ardhamagadhi. They were finally written down at the second Jain council held at Vallabhi in Gujarat under Devardhi Kshamashramana.

It is the Jain teaching that every object has countless aspects and that no single judgement can capture the whole truth.

The Buddha attained enlightenment seated under a peepal tree at Bodh Gaya, and the tree is therefore called the Bodhi tree; in early Buddhist art, where the Buddha was never shown in human form, the tree itself stands for the enlightenment.

After twelve years of severe austerity Mahavira attained kaivalya at the age of forty-two under a sal tree at Jrimbhikagrama, on the bank of the river Rijupalika, and from that moment was known as Jina and Kevalin.

Held in the reign of Ashoka under the presidency of Moggaliputta Tissa, it purged the order of dissenters, added the Abhidhamma Pitaka, the philosophical third basket, to the canon, and decided to send missionaries to Sri Lanka and other lands.

Parshvanatha had prescribed four restraints, and Mahavira added celibacy to them, so Jain monastic discipline rests on five great vows: ahimsa, satya, asteya, aparigraha and brahmacharya.

He was the twenty-third Tirthankara, a prince of Varanasi and son of King Ashvasena, whose emblem is the serpent. He is placed about two hundred and fifty years before Mahavira and gave his followers four vows: non-violence, truth, non-stealing and non-possession.

The Fourth Buddhist Council met at Kundalvana in Kashmir in the first century CE under the Kushana king Kanishka, with Vasumitra presiding and Ashvaghosha assisting him.

After his enlightenment the Buddha walked to the deer park at Sarnath near Varanasi and taught the Four Noble Truths to the five ascetics who had earlier deserted him.

Nife is formed from the chemical symbols of nickel and iron, the two metals believed to make up the central part of the planet, and the flow of that metal in the liquid outer core is what generates the Earth magnetic field.

Coal is a sedimentary rock formed from buried plant matter, and prolonged heat and pressure drive off its volatile content and rearrange the carbon, first into harder anthracite and finally into graphite, a metamorphic rock of nearly pure carbon.

It lies in the upper mantle just below the rigid outer shell, is weak and partly molten, and is the main source of the magma that reaches the surface through volcanoes; the plates slide over it.

The core bends P waves sharply and stops S waves altogether, so a belt of the Earth surface receives neither type of wave from a given earthquake.

Granite forms when magma cools slowly deep below the surface, which gives the crystals time to grow, so the rock is coarse and speckled.

It marks the change from the molten outer core to the solid inner core, and is named after Inge Lehmann, who deduced from the behaviour of earthquake waves that the innermost part of the planet is solid.

Almost half the weight of the crust, about 46.6 per cent, is oxygen, because it is locked into the silicate minerals of which nearly all crustal rocks are made rather than existing as free gas.
