The word klīm added to the gāyatrī mantra is explained in Brahma-saṁhitā as the transcendental seed of love of Godhead, or the seed of the kāma-gāyatrī. The object is Kṛṣṇa, who is the ever green Cupid, and by utterance of klīm mantra Kṛṣṇa is worshiped. It is also stated in the Gopāla-tāpanī Upaniṣad that when Kṛṣṇa is spoken of as Cupid, one should not think of Him as the Cupid of this material world. As already explained, Vṛndāvana is the spiritual abode of Kṛṣṇa, and the word Cupid is also spiritual and transcendental. One should not take the material Cupid and Kṛṣṇa to be on the same level. The material Cupid represents the attraction of the external flesh and body, but the spiritual Cupid is the attraction by which the Supersoul attracts the individual soul. Actually lust and sex are there in spiritual life, but when the spirit soul is embodied in material elements, that spiritual urge is expressed through the material body and is therefore pervertedly reflected. When one actually becomes conversant in the science of Kṛṣṇa consciousness, he can understand that his material desire for sex is abominable, whereas spiritual sex is desirable.
Spiritual sex is of two kinds: one in accordance with the constitutional position of the self and the other in accordance with the object. When one understands the truth about this life but is not completely cleansed of material contamination, he is not factually situated in the transcendental abode, Vṛndāvana, although he may understand spiritual life. When, however, one becomes free from the sex urges of the material body, he can actually attain the supreme abode of Vṛndāvana. When one is so situated, he can utter the kāma-gāyatrī and kāma-bīja mantra.
Rāmānanda Rāya then explained that Kṛṣṇa is attractive both for men and women, for the movable and the immovable—indeed, for all living entities. For this reason He is called the transcendental Cupid. Rāmānanda Rāya then quoted a verse from Śrīmad-Bhāgavatam (10.32.2) stating that when the Lord appeared before the damsels of Vraja smiling and playing on His flute, He appeared just like Cupid.
