दुर्लभ मनुस्या जीवन है,देह न बरम्बार ।
तरुवर ज्यों पत्ती झड़े,बहुरि न लागे डार ॥
Rare is the birth as a human being and one does not again again gets this human body. Once a leaf is detached from the trunk, cannot be joint back again.
In these two lines, Saint Kabir points out two universal truth and connects them together to point out the ultimate truth- a call to wake up for all the human beings.
The first line is a truth in itself. It is rare opportunity to get a human life. There are no proofs to show that there are many births. Neither are there any proofs to show that there is only one birth and nothing like soul exists. In other words, we are clueless and helpless as far as validity of the first line is concerned. But, when I look around, it makes sense to think that its an rare opportunity to be a human being. It even needs a better luck to be born as human being in an atmosphere and conditions where you can really live like a human being and not just survive like ainmals. So, this proves the first line of this doha of Saint Kabir.
The second line is more clear and striking. It says once a leaf is detached from the branch, it can never be attached to the tree again. In the context of the doha, it means, once this life is gone, once the soul is detached from the body, there is no way back. Everyone has to die a day. The leaf is going to be detached one day for sure. This precious human life will be taken away one day.
When these two lines of dohe of Kabir are contemplated together, it gives us a wake up call. The precious human life can come to an end and then you wont get an another chance. Once the leaf is detached, it is gone. In this doha, saint Kabir shows us the urgency of waking up fast and starting to act. In many of his dohe, Saint Kabir bluntly puts in front of us the way we waste our lives without sumiran (remembrance of the god). This doha once again points out this urgency and fragile nature of human life.
