AMERICAN MASTERS Series entitled Joni Mitchell: Woman of Heart and Mind.
Joni finds the most instructive piece of writing as to what LOVE is, and isn't, to be from the New Testament in The Bible. She quotes Paul from his writings to the Corinthians.
1 Corinthians chapter 13
(4) Love is patient, love is kind. It does not envy, it does not boast, it is not proud. (5) It is not rude, it is not self-seeking, it is not easily angered, it keeps no record of wrongs. (6) Love does not delight in evil but rejoices with the truth. (7) It always protects, always trusts, always hopes, always perseveres. (8) Love never fails. But where there are prophecies, they will cease; where there are tongues, they will be stilled; where there is knowledge, it will pass away. (9) For we know in part and we prophesy in part, (10) but when perfection comes, the imperfect disappears. (11) When I was a child, I talked like a child, I thought like a child, I reasoned like a child. When I became a man, I put childish ways behind me. (12) Now we see but a poor reflection as in a mirror; then we shall see face to face. Now I know in part; then I shall know fully, even as I am fully known. (13) And now these three remain: faith, hope and love. But the greatest of these is love.
