Sudama christina gives a beautiful example. He lived on the bank of the ganges, the gunga river and yould see these little boat plying. But until it catches the current, he has to work hard to push the boat into it. So how the current of spiritual life means when it becomes natural to us,. When you when the mind is now set in the new pattern, then you don't have to work so hard all the time. That is raga. Both are meant likes and dislikes. They color the mind, any kind of strong pull towards the world. I was amazed to read frid rewise old ast but htis pretty wise.
