This is an ancient Monotheistic religion based on the Hebrew Bible which includes the Torah. Jews believe that God created the universe, and he continues to work in the world and influence our everyday lives. More than that, Jews believe that god chose them as his chosen people in order to set an example of holiness. Also, Jews believe that Jesus of Nazareth did not fulfill messianic prophecies that establish the criteria for the coming of the Messiah.

Traditionally, Jews recite prayers three times daily including Shacharit, Mincha, and Ma’ariv with the fourth prayer of Mussaf on Shabbat and holidays. Jews recite prayers upon waking up in the morning, before eating or drinking different foods, and after eating a meal, etc.

As for clothing, you might have heard of Kippah which is a slightly rounded brimless skullcap. Jews wear Kippah while praying, eating, reciting blessings, studying Jewish religious texts, or at all times every day. Apart from that, there are Tzitzit (special knotted tassels), Tefillin (amulet), and Kittel (white knee-length overgarment).

Judaism, as a matter of fact, is a very family-centered religion as many of their traditions revolve around home like the Sabbath. To be a Jew is simple, you will be a Jew if you are a child of a Jewish woman. Also, even if you leave the faith, you still retain your Jewish status no matter what.

Buddhism is one of the most popular religions, especially among many countries in Asia. Buddhists follow the teachings of Gautama Buddha, the rich prince who left everything behind to achieve enlightenment. Buddhism originated in India sometime between the 6th and 4th century B.C after Gautama Buddha reached enlightenment under a pipal tree.
Buddhists believe that nothing is fixed or permanent, they also believe that change is always possible. All Buddhists live by the 5 Moral Precepts which are refraining from doing certain things in everyday life. That includes no harming living things, taking what is not given, sexual misconduct, lying or gossiping, and consuming alcohol or doing drugs.

As for Buddhist monks, they live by 10 precepts that involve their ways of living, eating, and associating with people. Therefore, monks are the people that Buddhists respect due to the refraining that they have followed. The interesting thing is that the celebration days of this religion are very joyful and colorful.

According to many scholars, Hinduism is the world’s oldest religion with roots and customs dating back more than 4,000 years. Hindus believe that Brahman is the one true god, but the religion also has thousands of lesser gods. Scholars suggest that Hinduism formally started somewhere between 2300 B.C and 1500 B.C in Indus Valley near Pakistan. Yet, many Hindus argue that their faith is timeless, and has always existed.

Hindus also believe that Brahman is present in all of us as the soul called Atman. Brahman encompasses all things including creation and destruction, male and female, good and evil, and movement and stillness. There are 3 parts to Brahman: Brahma (the creator), Shiva (the destroyer), and Vishnu (the preserver). The main goals of this religion are kama, artha, dharma, and moksha with each goal being more important than those before it.

Puja is Hindu Worship that takes place in the Mandir (temple), but followers can also worship at home and shrines. Giving offerings is an important part of Hindu worship, the offerings are flowers or oils to the god or goddess. The fascinating thing about this religion is its caste system that divides Hindus based on their karma and dharma. There are 4 main castes including:

  • Brahmin: the intellectual and spiritual leaders
  • Kshatriyas: the protectors and public servants of society
  • Vaisyas: the skillful producers
  • Shudras: the unskilled laborers

The caste system was very strict before India became an independent nation, but it is not so much now. However, there are still some traditions that still embrace marriage within their own specific caste.
