The Wheel of Dharma is one of the oldest and most popular symbols of Buddhism. In Sanskrit his name is Dharmacakra . It is very common to find this symbol on the doors of a Buddhist temple, on the altars, on the roofs of houses and even on the national flags of some countries like India.
 Note that the wheel itself is a symbol used by various religions and ideologies, as it means something that has no beginning or end and is not found in nature. The wheel was created by the human being and gives the idea of being in constant movement.
 The wheel is a metaphor for life itself, since it leads us to movement. According to the Buddhist reverend Sandro Vasconcelos:
 "To turn the Wheel, in short, is to transmit the Dharma, so that all diseases of the human soul are cured; keeping it in motion emphasizes the need that teaching must be exposed repeatedly and by skillful means, in order to facilitate assimilation of knowledge and benefit beings. "
 The Wheel of Dharma has eight rays that represent the Noble Eightfold Path which are the eight steps to achieve enlightenment. Are they:
 the correct understanding
 the right thought
 the correct way of speaking
 the correct action
 the correct way of life
 the correct effort
 the correct attention
 the correct concentration
 These were Buddha's first teachings to his disciples after several days of meditating. Pointed by him as the Middle Way , the wheel of Dharma led his followers to serenity, inner vision, enlightenment and fullness, which in Buddhism is called Nirvana .
 We observed that the Wheel of Dharma is made up of two circles. The largest represents Samsara or the "wheel of rebirth" in which we are prisoners. The smallest symbolizes Nirvana, when the final and definitive liberation from suffering is found and when we will have eternal happiness.
