The mood of the gopīs' emotional pursuit is called siddha-deha. This word indicates the pure spiritual body which is beyond the senses, mind and intelligence. Siddha-deha is the purified soul who is just suitable to serve the Supreme Lord. No one can serve the Supreme Lord as His associate without being situated in his pure spiritual identity. That identity is completely free from all material contamination. As stated in Bhagavad-gītā, a materially contaminated person transmigrates to another material body by material consciousness. At the time of death he thinks materially and is therefore transferred into another material body. Similarly, when one is situated in his pure spiritual identity and thinks of the spiritual loving service rendered to the Supreme Lord, he is transferred to the spiritual kingdom to enter into the association of Kṛṣṇa. In other words, by attaining one's spiritual identity and thinking of Kṛṣṇa's associates, one can become qualified to transfer to the spiritual kingdom. No one can contemplate or think of the activities of the spiritual kingdom without being situated in his pure, spiritual identity (siddha). Thus Rāmānanda Rāya said that without attaining siddha-deha, one can neither become an associate of the damsels nor render service directly to the Personality of Godhead, Kṛṣṇa, and His eternal consort Rādhārāṇī. In this regard, Rāmānanda quoted Śrīmad-Bhāgavatam (10.47.60):
- nāyaṁ śriyo 'ṅga u nitāntarateḥ prasādaḥ
- svar-yoṣitāṁ nalina-gandha-rucāṁ kuto 'nyāḥ
- rāsotsave 'sya bhujadaṇḍa-gṛhīta-kaṇṭha-
- labdhāśiṣāṁ ya udagād vraja-vallavīnām
"Neither the goddess of fortune, Lakṣmī, nor even the damsels of the heavenly kingdom can attain the facilities of the damsels of Vrajabhūmi—and what to speak of others."
