Buddhists have a new year ,But it is not January 1st.What is the reason they celebrate the new year of January 1st.It is based on a religious basis or something else...
...it is based on on something else...called Wisdom.
The Heart Sutra
Form does not differ from Emptiness And Emptiness does not differ from Form.
Form is Emptiness and Emptiness is Form
The Kalama Sutta sometimes also called the common sense sutta.
Kalamas, when you yourselves know: 'These things are good; these things are not blamable; these things are praised by the wise; undertaken and observed, these things lead to benefit and happiness,' enter on and abide in them.
There is suffering in life and it is unsatisfactory. In there if you find little reason to celebrate then celebrate without breaking the eight fold path. Afterall the Buddha never said 'dont look at the fireworks and feel happy'
Its all impermenant anyways. New year- No new year - Christian- Buddhist its all going to change. So dont take stuff too seriously. Live mindfully in the present moment. If the present moment brings you a celebration of new year then go for it.
If you meet a Buddha on the way kill the Buddha
Live like a lotus in mud. Dont get too much attached to ideas. Dont indulge into clinging, even for the Buddha. You have to let-go of everything. Even of Buddhism. Nirvana is in state of letting-go.
Buddha taught us to have sympathetic joy that is to rejoice in happiness of others. So if a Christian next door is gonna be happy for his New Year, Buddha told to go and enjoy his cake.
It's good to have a day that reminds one that another year has gone, has been wasted. That date differs also in traditional countries but in most of them people rush to celebrate it around the 13-16 April this days.
In nearly all regions it's related to a certain circle of decay in natures run around, seldom really "religious".
