Muthiyangana

Muthiyangana Vihara, Sri Lanka

At the southern end of Badulla stands the Muthiyangana Vihara whose origins date back 5th Century BC. Buddha is believed to have visited Lanka for the third time, on the eighth year following the supreme enlightenment. King Indaka of pre-historic (meaning prior to our recorded history) tribe Deva (one of the three tribes believed have inhabited Lanka, the other tribes being Yakka & Naga) built Muthiyangana stupa at the location where Buddha is believed to have made the sermons. The stupa was developed into a temple complex by a succession of Sinhalese kings commencing from King Devanam Piya Tissa (307-266 BC), The Deer Hunter, the first Sinhalese convert to Buddhism.

Dragon Arch at the entrance
The ancient Makara Torana (Dragon Arch) hasn't been dated. Mythological figures Vamana (a non-human ape like tribe believed have existed in India), Lion like beasts; bulls with very prominent humps decorate an arch unlike any other in Lanka.

Main Image House
Once again at the entrance to main image house (the house of status) is a colourful dragon arch with a statue of Maitree Bodhisattva, the next Buddha to be, according to the Mahayana Buddhism. The past Buddhas were Kakusanda, Konagama, Kassapa & Gauthama.

Guardian of the Muthiyangana
To the right of the image house is a statue of god Indaka, the guardian deity of Namunukula mountain range & Muthiyanga. Following his death, king Indaka of Naga tribe was elevated to a deity (most possibly, a superior being in another planet in cosmos) by virtue of his meritorious deeds. That is action & reaction. Lovely.

Muthiyangana Stupa
The stupa enshrines Sacred Kesha Datu, a lock of pure & blue-black, (Perhaps such could be the colour of the hair of an Asian man of perfect of health & purest of thought. Then again medieval Sinhalese poetry praising lissom women of matchless grace never fail to emphasise the colour of hair as bluish black) & Mutukuda datu (solidified sweat) of Buddha. The present 65m tall stupa with a diameter of 90m is a reconstruction of the original stupa. The moonstone at the entrance to the stupa is of Anurdadhapura Era.

Bo trees
The first Bo tree in to the temple complex called Maliyadeva bodhi is believed to be exact location where the last Maha Arhath (the enlightened one, who has broken free from the cycle of suffering of birth, & rebirth) Maliyadeva made the sermons on his visit to Muthiyangana. The second, Ananda Bodhi is believed to be brought from Jetavanarama in India. The third, Dethispala Sri Maha Bodhi was planted by King Devanam Piya Tissa.This is one of the 32 Bo trees originated from Sri Maha bodhi tree at Anuradhapura. It is well protected by the original fence & another newly built gold plated fence.

ArcGIS Desktop and ArcGIS Extensions come with tutorials and tutorial data to help you learn to use the software. You can use the links below to open PDF versions of the tutorials, or to view animations based on the tutorials.

ArcGIS Desktop Tutorials
The following tutorials are available in PDF format or as short animation files. To view the PDFs you need a copy of Adobe Reader, which you can download free from http://www.adobe.com/products/acrobat/readstep.html.

The tutorial data is available on the ArcGIS installation media. If the tutorial data has been installed on your system, look for it in C:\arcgis\ArcTutor (the default install location).
To view the animations you need the Adobe Flash Player which you can download free from http://www.adobe.com/go/getflashplayer.

ArcMap In this tutorial you'll learn how to display map features, add data to your map, edit geographic data, work with data tables, query and select geographic features, create a summary graph, and lay out and print a map Read the tutorial
ArcReader In this tutorial you'll learn how to view, explore, and print published maps. Read the tutorial

Watch the tutorial
ArcSDE Database Servers In this tutorial you will learn how to: add a database server and connect to it; add users and administer their permissions; create geodatabases and add data to them; administer database servers. Database servers are used to store, access, and administer ArcSDE Personal and Workgroup geodatabases. Read the tutorial

Watch the tutorial
Building Geodatabases In this tutorial you'll learn to build geodatabases that include relationship classes, subtypes, attribute domains, topology, geometric networks, feature-linked annotation, and dimension features. An ArcEditor or ArcInfo license is required to complete the tutorial. Read the tutorial

Watch the tutorial

Watch the tutorial
Linear Referencing In this tutorial you'll learn how to create, manage, display, query, and analyze data whose relative position has been modeled along a linear feature. Read the tutorial

Watch the tutorial
Representations In this tutorial, you will be introduced to representations which allow you to symbolize geographic features with a set of rules that are stored with your data in the geodatabase. Representation rules can create and draw dynamic geometry that differs from the feature shape, allowing a complex depiction of features without impacting the spatial integrity of your data. Representations provide greater control over the precision and definition of the symbolization of your data. Read the tutorial
