Mahamanah means very generous. Nanda Maharaja, who was very generous gave to all who came. Vidyopajivah refers to those who made a living by dancing, singing and play instruments, weapons and scripture etc. Tais tais kamaih means whatever was desired or asked. He gave suitably according to the level of their reputation and knowledge. The purpose of the charity was to worship Visnu in order to please Visnu, and for the auspiciousness of his son. "May Visnu be pleased by this charity, and by his pleasure, my son will be blessed."

He gave (verb understood) cloth and other items such as gold to the cowherd men and women, to the bards, and to singers and musicians as appropriate. He worshipped them appropriately. He was naturally generous but now became most devoted (mahāmanāḥ). As previously mentioned, because of his devotion to Kṛṣṇa, his qualities of generosity and wisdom increased immeasurably. He was not satisfied with giving, but whatever they desired he gave. He worshipped them according to caste, age and knowledge. He respected them with garlands, sandalwood, betel nut, and invitations. The purpose of giving is mentioned. It was for satisfying Viṣṇu not for going to Svarga, since he was the highest Vaiṣṇava and had reached the end of desiring any object. He gave for the welfare of his son. May Viṣṇu be pleased with this charity! May my son be prosperous by his mercy! By worshipping Viṣṇu, by that prosperity, there would be manifestation of Kṛṣṇa’s form, qualities and pastimes in his house. Mahāmanāḥ can also mean that his meditation became great because of developing attraction to Kṛṣṇa. Śukadeva has established the conclusion by the meaning of this verse, for the word ca means api to indicate Nanda’s rare position of getting Kṛṣṇa as his son. This established in later verses: nandaḥ kim akarod brahman śreya evaṁ mahodayam yaśodā ca mahā-bhāgā papau yasyāḥ stanaṁ hariḥ O learned brāhmaṇa, mother Yaśodā’s breast milk was sucked by the Supreme Lord. What past auspicious activities did she and Nanda Mahārāja perform to achieve such perfection in ecstatic love? SB 10.8.46 nemaṁ viriṣco na bhavo na śrīr apy aṅga-saṁśrayā prasādaṁ lebhire gopī yat tat prāpa vimuktidāt Neither Lord Brahmā, nor Lord Śiva, nor even the goddess of fortune, who is always the better half of the Supreme Lord, can obtain from the Supreme Lord, the deliverer from this material world, such mercy as received by mother Yaśodā. SB 10.9.20 yuvāṁ ślāghyatamau nūnaṁ dehinām iha māna-da nārāyaṇe ’khila-gurau yat kṛtā matir īdṛśī O respectful Nanda, certainly you and mother Yaśodā are the most praiseworthy persons in the entire world, since you have developed such a loving attitude toward Nārāyaṇa, the spiritual master of all living beings. SB 10.46.30

He gave (verb understood) cloth and other items such as gold to the cowherd men and women, to the bards, and to singers and musicians who made their living by their skills, as appropriate. He worshipped them appropriately. He was naturally generous but now became most devoted (mahāmanāḥ), knowing what they desired most or what was known as most excellent (tais taiḥ kāmaiḥ). Or he gave not only to those who made a living by their skills but also to the most unfortunate (anye). He gave not only gifts but respected everyone (ca). He worshipped all the brāhmaṇas and others. According to their birth and knowledge he satisfied their desires because he was generous. Or he worshipped them with desires which bring the Lord under control. That cannot be understood even by ātmārāmas, in order to satisfy the Lord. The plural “desires” is used to indicate respect or many desires. He worshipped for auspiciousness in this life and the next at the birth of his son, out of great affection, in order to satisfy Viṣṇu, since he was the best of devotees. Or he worshipped at the birth of his son for the highest goal (artha)--worshipping Viṣṇu. Actually the result of worshipping Viṣṇu was the birth of his son.
