From the holy book of Veda born more knowledge. One Jyothesa Vedāngga namely knowledge-based astronomy concepts Veda. In this situation the Hindu astronomy in earth orbit is calculated based on the content of the planet-planet space.
In general, the literature has two Hindu concept of the planet's orbit that affect the situation on the ground. Two concept, Surya Chandra Premana and Premana. Chandra Premana calculate time based on circulation month circumnavigate the earth. According to modern astronomy months circumnavigate the earth each month during the 29 days, 12 hours, 44 minutes. In a year, 12 months / sasih, 354/355 days. Surya Premana calculate time based on circumnavigate the earth orbit the sun in the year, 365 days, 5 hours, 48 seconds. This means that each year the system Chandra Premana faster than ten days Surya Premana system. In three years the system more quickly Premana Chandra 30 days.
To keep the system Premana Chandra and Surya Premana any adjustments, in astronomy in the Hindu Bali known concept of "nampih sasih." This concept is done by each of the three years there sasih Chandra system that is twice the sixty days. For example, if Wariga use Purwaning concept sasih the dilipatgandakan only Sasih Desta and Sasih Sada. With this system Sasih Kesanga always will be close to the moon by Caitra Surya Premana system. Caitra month that is identical to the March year CE.
The weather in this month's general torrential rain and not infrequently. Drop the form of rain that falls generally greater than on other sasih.
Circumnavigate the earth orbit the moon and the earth encircle the sun rise this afternoon and evening or morning, afternoon, evening and night. Science astronomy Bali called "wariga." In the academic year, "wariga" months or sasih called "time". Presence sasih the number of 12 is divided into two "period" that is "lahru period" means the summer, while winter is called "rengreng time."
In Sasih Karo around July the weather is generally quite cold, dry skin, so people gather in Bali, which is called "klaskasan." In the Third Sasih around August weather is dry kerontang drought. In Sasih Kapat around September drizzling rain began to fall, both untuh the growth of several types of plants. Interest-bungaan start to extract. In Sasih Kapat is called Sasih Kartika, according to Saka calendar system. So on each sasih have characteristics.
Hindu nation in Java and Bali have four calendar system that is generally oriented in the system and Surya Chandra Premana it. In addition to the permanent system using Chandra and Surya, the Hindu people in Bali and Java also have a system Wuku and Kertamasa system. Life, farming, trade and daily life is generally a good time is calculated based on four system calendar. For example, to work in agriculture known as the three systems, namely: System Kerta period of the season to plant the type of grain is done simultaneously by all citizens subak farmers; generally carried out in the Sasih Kapat, Kapitu and Kedasa (around October, January and April). System Ngagadon penenaman distraction as palawija plant, roots and vegetables. Ngagadong was also on Sasih Kapat, Kapitu and Kedasa. This is done simultaneously by farmers subak to restore soil fertility. Well tulak system, the system of farming that is not done concurrently by the farmers. This means that there are paddy, there palawija and there are also other. Generally, this is not good because it can reclaim the pest is very detrimental to farmers.
In addition to the time to arrange the farming life berekonomi system and other systems, wariga also set good time or "adult" to make life as to make the ceremony Panca Yadnya. Hindu people of Bali in doing Panca Yadnya generally use the system Wuku and Sasih the system, combined with Surya Premana and other sisterm as Wewaran or Dauh. Wuku of the system to know Kasih (of the Kliwon), Kliwon Buda, Buda Wage (Buda cemeng), Buda and Tumpek Manis (Saniscara Kliwon). System Chandra Purnama and recognize the existence of Tilem. Purnama generally for the Gods Yadnya. Tilem generally to Yadnya Bhuta.
For Gods Yadnya, sasih the most prominent generally used Purnama Sasih Kapat and Purnama Sasih Kedasa. For blind Yadnya most prominent Tilem Kesanga. Sasih Kesanga this month to meet with Caitra year, according to calculations using the system Saka Surya Premana. When Tilem Kesanga this Taur Kesanga ceremony held by the Hindu people in Bali in Indonesia and especially general. At the central level of public or state ceremony conducted by Taur Kesanga levels Tawur Agung. In this glorified levels pandita three groups. There pujanya to natural down that called Bhuwah Loka. There lacalderarock pandita intended to nature center called Bhuwah Loka and there lacalderarock pandita intended to natural called on the Swah Loka.
Taur ceremony Kesanga classified Bhuta Yadnya ceremony. In Lontar Agastia Parwa stated in the Java language Ancient follows: Bhuta Yadnya ngaran taur Muang kapujan Tuwuh ring. This means: Bhuta Yadnya is to restore and respect the vegetation. The definition of "taur" is to restore the natural order to perpetuate the situation again after used for the purpose of human life. For example, land used for farming after panen.kesuburan land must be returned as the original. How to plant with other plants that work to enrich the soil. Therefore, in the farming system in Bali is known Kerta system and the system Ngegadon period. The goal, to restore soil fertility. In Sarasamuscaya 135 to realize the stated purpose of life reach the Dharma, Artha, Kama and the earth in this first effort to Bhuta Hita means mensejahtrakan natural circumstances.
Taur Kesanga ceremony with the cult, led three groups pandita to life attitudes indoctrinate not do things that damage the natural three levels down, and the nature of the election. However, the fact that the sacred ritual stop at the level of the ritual with the whoopee-ray and is not able to generate power for diaktualkan in the spiritual life of the individual and social efforts do not damage the natural environment. Taur Kesanga ceremony should proceed with real efforts to save such as the use of natural resources, active in the conservation of natural resources. Thus the ceremony Taur Kesanga not a burden that weighed life and human nature in the earth.
The reality in this modern era of human very voracious exploit the natural pleasures of life for the moment. Users of natural resources and conservation efforts of natural resources is not done very balanced. The use of fresh water is excessive, while the vast forests and the quality is declining. Living with technological manghasilkan the abundant CO2 into the air. This has been causing air pollution. CO2 cause a rebound in the space close to the hot earth space. This is cause global warming continues to increase, which causes the north and south poles melt more. The natural process is not a natural cause of air pollution will increase. This raises what is called the "acid rain", namely acid rain. The dirty air is full of chemical substances dangerous, to meet cloudy alight acid rain. This acid rain damage to many plants such as banana shoots and coconut. Forest and agricultural crops also become damaged.
The use of substances prion that causes excess increasingly It ozone layer, which filter the sunlight to the earth. Sun no longer provide natural health-ray on living creatures. Weather is also increasingly difficult to be calculated based on the concept of astronomy or wariga that. Let the continued existence of the rights of human nature and human rights equally. Natural resources that were damaged will turn damage the human life of mankind on this earth.
