1. Prayer brings about change in oneself most of all, even without God's intervention.

2. Polio strikes irrespective of religion, caste or creed.

3. They seem to have to sing at different frequencies to overcome traffic noises

Explanation:

1. Prayer brings about change in oneself most of all, even without God's intervention.

Let's start by putting the subject first. This is a way to make the sentence easier to read and understand. 'Most of all' qualifies the first clause and introduces the final part of the sentence.

2. Polio strikes irrespective of religion, caste or creed.

Again, let's start with polio, the subject of the sentence. 'Irrespective' describes the first part of the sentence, so it comes next.  We then arrange religion, caste and creed based on punctuation and 'or.'

3. They seem to have to sing at different frequencies to overcome traffic noises.

We start again, with the subject of the sentence. This sentence can easily be divided into one shorter sentence and a clause: 'They seem to have to sing at different frequencies'  and 'overcome traffic noises.' The clause answers why they have to sing at different frequencies, which is the question that normally springs to mind if you hear the first sentence.
