Why is Kṛṣṇa worshipped with Rādhā and not with Rukmiṇī?

Rādhā is revered as the embodiment of pure love for Kṛṣṇa — his own joy-giving power — so devotion to him is often approached through her.

In Vraja traditions such as the Gauḍīya, Nimbārka, Vallabha and Rādhāvallabha sampradāyas, Rādhā is not simply a companion. She is Kṛṣṇa’s hlādinī śakti, the power of bliss, and the highest model of selfless love. Devotees greet one another with “Rādhe Rādhe” and believe that her grace draws Kṛṣṇa near. Jayadeva’s Gītagovinda made this love the heart of devotional poetry.

Rukmiṇī is Kṛṣṇa’s chief queen at Dvārakā and is worshipped with him there and in many temples, such as Paṇḍharpur, where Viṭṭhala stands with Rakhumāī. So both are honoured: Rādhā with the Vṛndāvana Kṛṣṇa of childhood and love, Rukmiṇī with the Dvārakā Kṛṣṇa as king.

At home, keep whichever form your family loves — Rādhā-Kṛṣṇa, Bāla Gopāla, or Kṛṣṇa alone. All are the same Lord.
