Srimad Bhagavatam
Philosophical research culminates in understanding the Supreme Personality of Godhead. After achieving this understanding, when one becomes free from the material modes of nature he attains the stage of devotional service. Either by devotional service directly or by philosophical research, one has to find the same destination, which is the Supreme Personality of Godhead.
A.C. Bhaktivedanta Swami Prabhupada
Anyone trying to enumerate or describe fully the unlimited qualities of the unlimited Supreme Lord has the intelligence of a foolish child. Even if a great genius could somehow or other, after a time-consuming effort, count all the particles of dust on the surface of the earth, such a genius could never count the attractive qualities of the Personality of Godhead, who is the reservoir of all potencies.
A.C. Bhaktivedanta Swami Prabhupada
Although fixed in His abode, the Personality of Godhead is swifter than the mind and can overcome all others running. The powerful demigods cannot approach Him. Although in one place, He controls those who supply the air and rain. He surpasses all in excellence.
Bhaktisiddhanta Sarasvati Thakura
Krishna is the supreme personality of godhead and cause of all causes. He is original creator, maintainer, and annihilator of all universes. Lord Brahma and Lord Rudra are empowered secondary agents under the instructions of Krishna.
A.C. Bhaktivedanta Swami Prabhupada
All the demigods and all the philosophers who desire liberation bow down to the Supreme Personality of Godhead.
Srimad Bhagavatam
Although the motive (of a devotee) might be impure, the Lord does not consider the motive; He is concerned with the service. However if a devotee has a particular motive, the Lord directly or indirectly knows it and therefore, He does not leave the devotee’s material desire unfulfilled. These are some of the special favours by the Lord to a devotee.
