The two breasts represent attachment and envy. The symptoms of rāga and dveṣa (attachment and envy) are described in Bhagavad-gītā (BG 3.34):
- rāga-dveṣau vyavasthitau
- tayor na vaśam āgacchet
- tau hy asya paripanthinau
"Attraction and repulsion for sense objects are felt by embodied beings, but one should not fall under the control of senses and sense objects because they are stumbling blocks on the path of self-realization."
These representatives of attachment and envy are very much unfavorable for advancement in spiritual life. One should not be attracted by the breasts of young women. The great saint Śaṅkarācārya has described the breasts of women, especially young women, as nothing but a combination of muscles and blood, so one should not be attracted by the illusory energy of raised breasts with nipples. They are agents of māyā meant to victimize the opposite sex. Because the breasts are equally attractive, they are described as sama-vṛttau. The sex impulse remains in an old man's heart also, even up to the point of death. To be rid of such agitation, one must be very much advanced in spiritual consciousness, like Yāmunācārya, who said:
- yad-avadhi mama cetaḥ kṛṣṇa-pādāravinde
- nava-nava-rasa-dhāmany udyataṁ rantum āsīt
- tad-avadhi bata nārī-saṅgame smaryamāṇe
- bhavati mukha-vikāraḥ suṣṭhu niṣṭhīvanaṁ ca
"Since I have been engaged in the transcendental loving service of Kṛṣṇa, realizing ever-new pleasure in Him, whenever I think of sex pleasure, I spit at the thought, and my lips curl with distaste." When one is spiritually advanced he can no longer be attracted by the lumps of flesh and blood which are the breasts of young women. The word nirantarau is significant because although the breasts are situated in different locations, the action is the same. We should not make any distinction between attachment and envy. As described in Bhagavad-gītā (BG 3.37), they are both products of rajo-guṇa (kāma eṣa krodha eṣa rajo-guṇa-samudbhavaḥ).
The word nigūhantīm ("trying to cover") indicates that even if one is tainted by kāma, lobha, krodha, etc., they can be transfigured by Kṛṣṇa consciousness. In other words, one can utilize kāma (lust) for serving Kṛṣṇa. Being impelled by lust, an ordinary worker will work hard day and night; similarly a devotee can work hard day and night to satisfy Kṛṣṇa. Just as karmīs are working hard to satisfy kāma-krodha, a devotee should work in the same way to satisfy Kṛṣṇa. Similarly, krodha (anger) can also be used in the service of Kṛṣṇa when it is applied to the nondevotee demons. Hanumānjī applied his anger in this way. He was a great devotee of Lord Rāmacandra, and he utilized his anger to set fire to the kingdom of Rāvaṇa, a nondevotee demon. Thus kāma (lust) can be utilized to satisfy Kṛṣṇa, and krodha (anger) can be utilized to punish the demons. When both are used for Kṛṣṇa's service, they lose their material significance and become spiritually important.
