"A king is always accompanied by his ministers, secretaries and commanders, and Lord Visnu is also accompanied by His followers--the demigods, great sages, saintly persons and so on. He is never alone. Consequently there is no question of the Lord's being impersonal. He is always Himself, the Supreme Personality of Godhead, and His associates are also persons
Srimad-Bhagavatam 4:30:6 Purport
"Pure devotees of the Lord are all bhavas, or persons who know the glories of the Lord in different transcendental loving services. As the Lord has innumerable expansions of His plenary form, there are innumerable pure devotees of the Lord, who are engaged in the exchange of service of different humors. Ordinarily there are twelve great devotees of the Lord, namely Brahma, Narada, Siva, Kumara, Kapila, Manu, Prahlada, Bhisma, Janaka, Sukadeva Gosvami, Bali Maharaja and Yamaraja.
...Srila Visvanatha Cakravarti Thakura, one of the great acaryas in the modern age, explains that anubhava, or the glory of the Lord, is first appreciated by the devotee in ecstasy manifesting the symptoms of perspiring, trembling, weeping, bodily eruptions, etc., which are further enhanced by steady understanding of the glories of the Lord. Such different understandings of bhavas are exchanged between Yasoda and the Lord (binding the Lord by ropes) and in the chariot driving by the Lord in the exchange of love with Arjuna. These glories of the Lord are exhibited in His being subordinated before His devotees, and that is another feature of the glories of the Lord. Sukadeva Gosvami and the Kumaras, although situated in the transcendental position, became converted by another feature of bhava and turned into pure devotees of the Lord. Tribulations imposed upon the devotees by the Lord constitute another exchange of transcendental bhava between the Lord and the devotees. The Lord says "I put My devotee into difficulty, and thus the devotee becomes more purified in exchanging transcendental bhava with Me." Placing the devotee into material troubles necessitates delivering him from the illusory material relations. The material relations are based on reciprocation of material enjoyment, which depends mainly on material resources. Therefore, when material resources are withdrawn by the Lord, the devotee is cent percent attracted toward the transcendental loving service of the Lord. Thus the Lord snatches the fallen soul from the mire of material existence. Tribulations offered by the Lord to His devotee are different from the tribulations resulting from vicious action. All these glories of the Lord are especially known to the great mahajanas like Brahma, Siva, Narada, Kapila, Kumara and Bhisma, as mentioned above, and one is able to grasp it by their grace."
Srimad-Bhagavatam 1:9:`9 Purport
"As stated in the Brahma-samhita, Lord Krsna is the Supreme Lord. No one is greater than Him; He is the cause of all causes. Here it is also stated by the Lord personally that He is the cause of all the demigods and sages. Even the demigods and great sages cannot understand Krsna; they can understand neither His name nor His personality, so what is the position of the so-called scholars of this tiny planet? No one can understand why this Supreme God comes to earth as an ordinary human being and executes such commonplace and yet wonderful activities. One should know, then, that scholarship is not the qualification necessary to understand Krsna. Even the demigods and the great sages have tried to understand Krsna by their mental speculation, and they have failed to do so. In the Srimad-Bhagavatam also it is clearly said that even the great demigods are not able to understand the Supreme Personality of Godhead. They can speculate to the limits of their imperfect senses and can reach the opposite conclusion of impersonalism, of something not manifested by the three qualities of material nature, or they can imagine something by mental speculation, but it is not possible to understand Krsna by such foolish speculation.
Bhagavad-gita 10:2 Purport
"The devotees of Lord Visnu offer all kinds of sacrifices for His pleasure. The devotees are always attached to the service of the Lord, whereas fallen souls are attached to the pleasures of material existence. In Bhagavad-gita, it is said that anything performed in the material world for any reason other than for the pleasure of Lord Visnu causes further bondage for the performer. It is enjoined therefore that all acts must be performed sacrificially for the satisfaction of Visnu and His devotees. This will bring everyone peace and prosperity.
The great sages are always anxious to do good to the people in general... Forgetful men do not know the right path for peace and prosperity. However, the sages know it well, and therefore for the good of all men they are always anxious to perform acts which may bring about peace in the world. They are sincere friends to all living entities, and at the risk of great personal inconvenience they are always engaged in the service of the Lord for the good of all people."
