"If you have learnt to long, by pain
be not distressed-
Secret of love's sorrow must be
Suffering is by the heart caressed,
and there it is preserved."
OK! I got this:
If you are suffering and you have got no one with whom you can share the suffering (or cause of the sorrow), don't worry! You don't need to confess it. Keep it in your heart as there is no place and friend better than your own heart!
Now the part i didn't get is why is he saying that secret of love's sorrow must not be shared with anyone but your heart?
To me, one should share everything with people around you. It helps others and you yourself as well to get better understanding of certain things and experiences.
Sooo... To understand his concept:
1-Your heart here may mean everyone
2-This sorrow may be of different type, may be it is "flipped"... err... opposite i mean. By sharing sorrow, you feel good, but in this case, you may feel better by "not sharing" it.
3-Protect this suffering. It may be an asset!
These are still "may-s".
Are these true? What do you people think?
