The effulgent Sun can be seen only with his own light. Similarly, only by the grace of the Divine can one obtain a vision of the Divine. No skill, intellectual effort or scholarship is required to experience the Divine. Just as clouds may obscure the Sun, the clouds of egoism, attachment and hatred prevent one from seeing the Divine. Prayer and Spiritual discipline are the means by which these clouds are dispersed. Spiritual discipline is the royal road to reach the Divine.
