And their idea of perfection is self annihilation.
And you don't know anything about Buddhism. I encourage you to learn about it instead of making yourself look particularly ignorant.
The 4 noble truths Straight from the Buddha’s mouth:
1. Dukkha: The purpose of life is to suffer. We suffer in this life for the sins in our past life.
2. Samudaya: Sin is being attached to this world (Universe)which taught by Buddhism to be an illusion.
3. Nirodha: The way to end suffering (Stop being reincarnated) is to give up everything (All reality is an illusion this is why the Buddha’s eyes are always closed there is nothing worth seeing)
4.Magga: The use of meditation and self-denial is the means to enlightenment and the way to overcome the wheel of Samsara. The mantra brings the individual to perfect nothingness. No personality, no knowing, now pain no good or evil. When the Buddha talks of joining with nothingness he meant a vacuum, a complete and total void.
It is a depressing philosophy and totally fatalistic. Buddhist appear calm because literally nothing is worth more than something
This is the basic teaching of Buddhism.
By the way: Reincarnation, as described in the Buddhist text, is logically, metaphysically and mathematically impossible.
