Translation: 
What to speak of others, even Lord Baladeva, the Supreme Personality of Godhead, is full of emotions like pure friendship and paternal love.
Purport: 

Although Lord Baladeva appeared before the birth of Lord Kṛṣṇa and is therefore Kṛṣṇa’s worshipable elder brother, He used to act as Kṛṣṇa’s eternal servitor. In the spiritual sky all the Vaikuṇṭha planets are predominated by the quadruple expansions of Kṛṣṇa known as the catur-vyūha. They are direct expansions from Baladeva. It is the singularity of the Supreme Lord that everyone in the spiritual sky thinks himself a servitor of the Lord. According to social convention one may be superior to Kṛṣṇa, but factually everyone engages in His service. Therefore in the spiritual sky or the material sky, in all the different planets, no one is able to supersede Lord Kṛṣṇa or demand service from Him. On the contrary, everyone engages in the service of Lord Kṛṣṇa. As such, the more a person engages in the service of the Lord, the more he is important; and, conversely, the more one is bereft of the transcendental service of Kṛṣṇa, the more he invites the bad fortune of material contamination. In the material world, although materialists want to become one with God or compete with God, everyone directly or indirectly engages in the service of the Lord. The more one is forgetful of the service of Kṛṣṇa, the more he is considered to be dying. Therefore, when one develops pure Kṛṣṇa consciousness, he immediately develops his eternal servitorship to Kṛṣṇa.
