Srimad Bhagavadgita Sadhaka Sanjivani -Swami Ramsukhdas
Now a doubt arises, why were the three worlds greatly alarmed and trembling with fear? Did the beings of the three worlds, also behold, the cosmic form? And if they beheld, it then how?
In fact, the entire universe is a fragment of the cosmic form, of the Lord. The transience and modifications that appear in the universe, are nothing but, the sport of the Lord. The Lord, as well as his cosmic form, has His independent existence, while the universe has no independent existence of its own. Arjuna saw the cosmic form of the Lord, with divine eyes, while devotees perceive this universe, as the manifestation of the Lord.
