且将前尘饮
[qiĕ jiāng qián chén yĭn]
'Drink the Dust of Previous Life' means drinking down one's past or previous experiences like dust. It implies a certain kind of nostalgia mixed with indifference: not forgetting, but no longer overly clinging to the things happened before, accepting both the good and bad that have come to pass as inevitable events in one's lifetime.
