The Six Horizons of Buddhism refer to the six desires and greed that appear in practice. They are horizon, ear, nose, tongue, body and mind respectively. These desires and greed are inherent in us human beings and make us indulge in the secular world. In Buddhist practice, we need to get rid of these desires and greed in order to truly realize the path of nirvana.
Horizon is the persistence of foreign countries in the world, and we believe that having more material wealth and enjoyment is the purpose of our life. Ear boundary is the obsession with sound, which makes us attracted by entertainment programs and meaningless chat. The nasal boundary is the obsession with smell, which makes us indulge in the taste of perfume and food. Tongue boundary is the persistence of food, which makes us pursue excessive diet and enjoyment. The cross of the body is the persistence of material things, which makes us pursue fame and wealth and rights. However, the horizontal boundary of meaning is a manifestation of self-attachment, which makes us addicted to our own desires and thoughts.
The emergence of the Six Horizons of Buddhism is due to the defects of human nature, which makes us unable to get rid of our obsession with matter and ideas. But in practice, we need to get rid of these desires and greed gradually through meditation and mindfulness practice. Only when we face up to our inner desires and greed, can we really get the way of nirvana, achieve spiritual purification and liberation, and achieve real happiness and peace.
