The law of karma continues birth after birth, and when there is a new creation, the same karma comes back with the living entities. They are born in different capacities according to karma even though their father is originally Brahmā, who is the exalted qualitative incarnation of the Supreme Personality of Godhead.

If one hears and again narrates, with faith and devotion, this story of the Dakṣa yajña as it was conducted by the Supreme Personality of Godhead, Viṣṇu, then certainly one is cleared of all contamination of material existence, O son of Kuru.

Lord Rudra, Śiva, was properly worshiped with his share of the remnants of the yajña. Yajña is Viṣṇu, and whatever prasāda is offered to Viṣṇu is offered to everyone, even to Lord Śiva. Śrīdhara Svāmī also comments in this connection, svena bhāgena: the remnants of the yajña are offered to all the demigods and others.

The devotee who is highly elevated sees the relationship to Kṛṣṇa in everything; he does not see anything as being independent of Kṛṣṇa. That is his vision of oneness.

In order to achieve real peace, one should see everything and every living entity, including Lord Brahmā and Lord Śiva, as nondifferent from the Supreme Personality of Godhead. No one is independent. Every one of us is an expansion of the Supreme Personality of Godhead. This accounts for unity in diversity.

Whenever there is disease in any part of the body, the whole body takes care of the ailing part. Similarly, a devotee’s oneness is manifested in His compassion for all conditioned souls.

The living entities, including Brahmā, are not independently separated, but are counted within the marginal potency of the Supreme Lord. The Supreme Lord, being the Supersoul in every living entity, including Lord Brahmā and Lord Śiva, is directing everyone in the activities of the material modes of nature.

Nityananda Trayodashi Special morning lecture

Lord Brahmā and Lord Śiva are qualitative incarnations of Viṣṇu, as guṇa-avatāras, and Viṣṇu with them accepts control of the quality of goodness; therefore He is also a qualitative incarnation like Lord Śiva and Lord Brahmā. Actually the different names exist for different directions; otherwise the origin is one only.

Everything is generated from Lord Viṣṇu, everything is maintained by Him, and everything is annihilated by His energy. Therefore, by their actions and reactions, the energies which come from Him create the cosmic manifestations and also dissolve the whole creation. Thus the Lord is the cause and also the effect.
