Idols are quite specific. But your will is universal, being limitless. And so it has no form, nor is content for its expression in the terms of form.
It’s hard to grasp the underlined part…..
Is that to be understood (A) Your will has no form, and also your will is not contented with your will’s expression in terms of form”?
(B) Your will has no form, and your will is not contented with your will’s expression in terms of form”?
(C) Your will has no form, and content is not for your will’s expression in terms of form”?
