Neruda, Tagore and Iqbal

We can draw a parallel line between the three great national poets, most popular in their respective continents. Rabindranath Tagore can thus be regarded as having an effective visual perception regarding perceptual realism. One can recognise the factor that the poet had his greatest association with Hindu theology. However, if we draw a similar association with the Chilean author and poet Pablo Neruda and of-course no-body can actually forget Iqbal, then one can thus obtain the idea that the functional prowess of their national poetry has not only continued to influence their respective religious ideologies, but their inclination towards their respective beliefs can also be seen.
But still Tagore, Neruda and Iqbal, all of them possessed a similar homogeneity in their styles and expressions.
