Srimad Bhagavatam SB 3.5.15-16 Speaker - H.G. Balaram Das

ŚB 3.5.15
tad asya kauṣārava śarma-dātur
hareḥ kathām eva kathāsu sāram
uddhṛtya puṣpebhya ivārta-bandho
śivāya naḥ kīrtaya tīrtha-kīrteḥ

Synonyms
tat — therefore; asya — His; kauṣārava — O Maitreya; śarma-dātuḥ — of one who awards good fortune; hareḥ — of the Lord; kathām — topics; eva — only; kathāsu — of all topics; sāram — the essence; uddhṛtya — by quoting; puṣpebhyaḥ — from the flowers; iva — like that; ārta-bandho — O friend of the distressed; śivāya — for welfare; naḥ — of us; kīrtaya — kindly describe; tīrtha — pilgrimage; kīrteḥ — of glorious.

Translation
O Maitreya, O friend of the distressed, the glories of the Supreme Lord can alone do good for people all over the world. Therefore, just as bees collect honey from flowers, kindly describe the essence of all topics — the topics of the Lord.

Purport
There are many topics for different persons in different modes of material nature, but the essential topics are those in relationship with the Supreme Lord. Unfortunately, materially affected conditioned souls are all more or less averse to topics of the Supreme Lord because some of them do not believe in the existence of God and some of them believe only in the impersonal feature of the Lord. In both cases there is nothing for them to say of God. Both the nonbelievers and the impersonalists deny the essence of all topics; therefore, they engage in topics of relativity in various ways, either in sense gratification or in mental speculation. For the pure devotees like Vidura, the topics of both the mundaners and the mental speculators are useless in all respects. Thus Vidura requested Maitreya to talk of the essence only, the talks of Kṛṣṇa, and nothing else.

ŚB 3.5.16
sa viśva-janma-sthiti-saṁyamārthe
kṛtāvatāraḥ pragṛhīta-śaktiḥ
cakāra karmāṇy atipūruṣāṇi
yānīśvaraḥ kīrtaya tāni mahyam

Synonyms
saḥ — the Personality of Godhead; viśva — universe; janma — creation; sthiti — maintenance; saṁyama-arthe — with a view to perfect control; kṛta — accepted; avatāraḥ — incarnation; pragṛhīta — accomplished with; śaktiḥ — potency; cakāra — performed; karmāṇi — transcendental activities; ati-pūruṣāṇi — superhuman; yāni — all those; īśvaraḥ — the Lord; kīrtaya — please chant; tāni — all those; mahyam — unto me.

Translation
Kindly chant all those superhuman transcendental activities of the supreme controller, the Personality of Godhead, who accepted incarnations fully equipped with all potency for the full manifestation and maintenance of the cosmic creation.

Purport
Vidura was undoubtedly very eager to hear about Lord Kṛṣṇa in particular, but he was overwhelmed because Lord Kṛṣṇa had just passed away from the visible world. He therefore wanted to hear about Him in His puruṣa incarnations, which He manifests with full potencies for the creation and maintenance of the cosmic world. The activities of the puruṣa incarnations are but an extension of the activities of the Lord. This hint was given by Vidura to Maitreya because Maitreya could not decide which part of the activities of Lord Kṛṣṇa should he chanted.
