Indian Flag: meaning of the tricolour?

Posted Date : 6/27/2012

The national flag – the tricolor – we stand to attention before it as the national anthem plays out, we proudly cheer our teams as they carry it at the opening ceremonies of international games, but how much do we really know about our own flag? Who designed it? Pingali Venkaya, a writer and geophysicist from Andhra Pradesh, designed the flag in 1916. The color and design underwent several modifications in 1921, 1931, and then in 1947 when the ‘Charka’ in the middle was replaced by the ‘Chakra’. Why 3 colors? Spiritual symbolism Saffron embodies courage, sacrifice, and the spirit of renunciation. White symbolizes unity, purity, and peace. Dr. Radhakrishnan, India’s first Vice President said of the white color, “The white in the centre is light, the path of truth to guide our conduct.” Green represents fertility and prosperity of the land. The ‘Chakra’ is the symbol of law and progress. Of this, Dr. Radhakrishnan said, “…the wheel denotes motion… represents the dynamism of a peaceful change. The 24 spokes symbolize twenty-four hours of the day.”

Good Friday

Posted Date : 4/7/2012

Good Friday is the Friday immediately preceding Easter Sunday. It is celebrated traditionally as the day on which Jesus was crucified. If you are interested in a study of the issue, please see our article that discusses the various views on which day Jesus was crucified. Assuming that Jesus was crucified and died on a Friday, should Christians remember Jesus~ death by celebrating Good Friday? The Bible does not instruct Christians to remember Christ’s death by honoring a certain day. The Bible does give us freedom in these matters, however. Romans 14:5 tells us, “One man considers one day more sacred than another; another man considers every day alike. Each one should be fully convinced in his own mind.” Rather than remembering Christ~s death on a certain day, once a year, the Bible instructs us to remember Christ’s death by observing the Lord’s Supper. First Corinthians 11:24-26 declares, “...do this in remembrance of me...for whenever you eat this bread and drink this cup, you proclaim the Lord~s death until he comes.” Why is Good Friday referred to as “good”? What the Jewish authorities and Romans did to Jesus was definitely not good (see Matthew chapters 26-27). However, the results of Christ’s death are very good! Romans 5:8; “But God demonstrates his own love for us in this: While we were still sinners, Christ died for us.” First Peter 3:18 tells us, “For Christ died for sins once for all, the righteous for the unrighteous, to bring you to God. He was put to death in the body but made alive by the Spirit.” Many Christian churches celebrate Good Friday with a subdued service, usually in the evening, in which Christ’s death is remembered with solemn hymns, prayers of thanksgiving, a message centered on Christ suffering for our sakes, and observance of the Lord~s Supper. Whether or not Christians choose to “celebrate” Good Friday, the events of that day should be ever on our minds because the death of Christ on the cross is the paramount event of the Christian faith.

new year

Posted Date : 12/24/2011

In India, the New Year arrives with the onset of the Festival of Lights, known as Deepawali or Diwali. It marks the beginning of the Hindu New Year. This festival is celebrated with a great zeal, enthusiasm and joy throughout the country. Diwali signifies the victory of good over evil, in Hindu religion. It is celebrated in different ways in different regions of India and is the biggest Hindu festival in the country. People worship the deities, distribute sweets and burst crackers on this day and relatives visit each other to give best wishes for Diwali. However, the celebrations have a deep religious history, based on Hindu mythology. In major parts of North India, it is believed that Diwali is celebrated to mark Lord Ram~s return to Ayodhya, after slaying the demon king Ravana. It is widely believed that the people of Ayodhya lit small earthenware lamps to light up the streets of the town and this tradition has been kept alive till now. Diwali is usually celebrated during the months of October-November. In the east, the festival is devoted to Goddess Lakshmi, the deity of wealth and also to Goddess Kali, a reincarnation of Lakshmi. The festival is famously known as ~Durga Puja~ in East India. The festivities in the east extend to two to three days. In South India, New Year falls in the month of "Chittirai", which lasts from April 14 to May 14. New Year is usually celebrated on the 14th of April and is popularly known as "Vishu" and "Tamizh puthaandu". The day begins with an elaborate puja of household articles, ranging from food and clothes to gold jewelry. An elaborate feast is prepared and the entrances of homes are decorated with flowers and the traditional ~rangolis~ called "kolam". Celebrators also offer home made snacks to the guests and visitors. In Maharashtra, locals celebrate Gudi Padwa as the New Year, while in Andhra Pradesh and Karnataka, it is known as Ugadi. The timing of Ugadi and Gudi Padwa celebrations is the same i.e. the month of Chaitra. In Kashmir, the lunar New Year is known by the name of ~Navroh~. The celebrations coincide with the first day of Chaitra. In Orissa, New Year is celebrated as Mahabishuba Sankranti. On this day, Oriya people offer a sweet drink, known as Pana, to the holy plant Tulsi, Lord Shiva and other deities. While customs and traditions of New Year may vary across the various parts of the country, the basic essence behind celebrating the New Year remains the same.

Noisy times and quiet times

Noisy times and quiet times Sweet Spring Spring is sweet because we can go boat riding and bees come and take honey out of the flowers. I feel good because it is very, very, very hot outside and I can go on the swings. The best part of spring is that my family can go to the beach.
