Make Thin

[MahaB82A]

There are two separate texts group together. I want to make it thin text. As it is two texts, make one text thin is not effect to other text. How to do it both together?

If you proportionally scale the circle that you have selected, then the result should be a thinner blend along the path. Is that what you mean?

As @Myra Ferguson has already said: In your screenshot, a circle is selected. Reduce the size of this selected circle (by transforming or by scaling or by dragging smaller with the mouse + Shift).
