Human life is (1) _______ a unique blessing, which in turn depends on the (2) _______ of the Self. He who is not aware of the Self can neither have peace nor can he foster peaceful co-existence. We have to link our soul with God and body with the physical world for substance. (3) _______ the formless God is invisible to the naked eye, our mind often wanders wherever it goes. (4) _______ , we are unable to develop any love for the Divine. And religion like the white light of heavens (5) _______ multi-coloured fragmentations by the prisms of men and loses its gravity.

Select the most appropriate option to fill in blank no. 4.

To determine the most appropriate option for blank (4), we need to analyze the logical relationship between the preceding sentence and the sentence containing the blank:
1. Preceding context: "...our mind often wanders wherever it goes." This describes the cause: since the formless God is invisible to the naked eye, our attention and thoughts drift away.
2. Succeeding context: "_______ , we are unable to develop any love for the Divine." This describes the direct consequence or outcome of our wandering minds.

We need a transition phrase that indicates a cause-and-effect or sequential relationship:
- "As a result" is a cohesive device used to introduce a logical consequence or outcome of a previously stated event, which fits the context perfectly.
- "As a reaction" implies an active counter-response to an action, which does not fit the cause-and-effect logic of the passage.
- "Causing" is a participle and cannot grammatically introduce a new independent clause in this position (followed by a comma and a subject-verb structure).
- "As a reason" is grammatically incorrect for introducing a consequence.

Therefore, the correct choice to establish the proper logical connection is As a result.
