Due to a poor fund of knowledge, the mental speculators try to bring the Supreme within the purview of words and minds, but the Lord refuses to be so intelligible; the speculator has no adequate words or mind to gauge the infinity of the Lord. The Lord is called adhokṣaja, or the person who is beyond perception by the blunt, limited potency of our senses. One cannot perceive the transcendental name or form of the Lord by mental speculation. The mundane Ph.D.’s are completely unable to speculate on the Supreme with their limited senses. Such attempts by the puffed up Ph.D’s are compared to the philosophy of the frog in the well. A frog in a well was informed of the gigantic Pacific Ocean, and he began to puff himself up in order to understand or measure the length and breadth of the Pacific Ocean. Ultimately the frog burst and died. The title Ph.D. can also be interpreted as Plough Department, a title meant for the tillers in the paddy field. The attempt of the tillers in the paddy field to understand the cosmic manifestation and the cause behind such wonderful work can be compared to the endeavor of the frog in the well to calculate the measurement of the Pacific Ocean.
The Lord can reveal Himself only to a person who is submissive and who engages in His transcendental loving service. The demigods controlling the elements and ingredients of universal affairs prayed to the Lord for guidance, and thus He manifested His gigantic form, as He did at the request of Arjuna.
