Out of these five basic subject matters in Bhagavad-gītā it is established that the Supreme Godhead, or Kṛṣṇa, or Brahman, or the supreme controller, or Paramātmā—you may use whatever name you like—is the greatest of all. The living beings are in quality like the supreme controller. For instance, the Lord has control over the universal affairs of material nature, as will be explained in the later chapters of Bhagavad-gītā. Material nature is not independent. She is acting under the directions of the Supreme Lord.
