The Maitrakas were a dynasty of rulers who ruled Gujarat in western India from the 5th to the 8th centuries CE. They were patrons of Hinduism, and many of their temples and sculptures are still found in Gujarat today. The Maitrakas were particularly devoted to the god Shiva, and many of their temples are dedicated to him.
Jainism is a religion that originated in India in the 6th century BCE. It is based on the teachings of Mahavira, who is considered to be the 24th Tirthankara, or spiritual teacher. Jains believe in non-violence, non-attachment, and renunciation. They practice vegetarianism and avoid harming any living creature.
Buddhism is a religion that originated in India in the 6th century BCE. It is based on the teachings of Siddhartha Gautama, who is also known as the Buddha. Buddhists believe that suffering is caused by attachment and desire, and that the way to end suffering is to follow the Eightfold Path.
Zoroastrianism is a religion that originated in Persia in the 6th century BCE. It is based on the teachings of Zoroaster, who is considered to be the founder of the religion. Zoroastrians believe in one supreme god, Ahura Mazda, and in the struggle between good and evil.
The Maitrakas were not patrons of Jainism, Buddhism, or Zoroastrianism.
