Puruṣa means the enjoyer. So here in this material world, either the so-called man and so-called woman, everyone is hankering after sense enjoyment. Therefore all of them together has been described as puruṣa. A woman is not puruṣa, but by mentality she is puruṣa, because she also wants to enjoy. Although she has got the body of being enjoyed, but she has the mentality of enjoying. Therefore everyone is described, although by nature everyone is prakṛti, not puruṣa. Prakṛti means enjoyed. That is stated in the Bhāgavata, prakṛti me bhinnā aṣṭadhā. This material body is made of earth, water, fire, air, sky. That is prakṛti. Bhinnā, separated. Itas tu viddhi me prakṛtiṁ parām (BG 7.5). There is another nature, that is parā prakṛti. That is spiritual nature. And how I can understand? Now jīva-bhūta. You can understand that parā-prakṛti is the living entity, yayedaṁ dhāryate jagat (BG 7.5), which is sustaining this material nature. So actually in the Bhagavad-gītā they..., both of us are described as prakṛti, not puruṣa. Puruṣa is Kṛṣṇa. Therefore Arjuna, when he realized after reading Bhagavad-gītā, he addresses Kṛṣṇa as puruṣa. Paraṁ brahma paraṁ dhāma pavitraṁ paramaṁ bhavān, puruṣa śāśvata (BG 10.12). We are..., not that you have become puruṣa now, but śāśvata, eternal.
Just like here, we are puruṣa. This birth I am puruṣa; next birth I may become stri or prakṛti. If I am too much fond of woman, and at the time of death, if I think of woman, then I get a woman's body. Yaṁ yaṁ vāpi smaran bhāvaṁ tyajanty ante kalevaram (BG 8.6). Therefore too much attachment for woman is not good, because... Or too much attachment for anything in this material world, that is doomed. Therefore, here it is said, hṛdaya-granthi-bhedanam. Hṛdaya-granthi-bhedanam. "My attachment, my heart attraction, is so strong, it is like granthi, knot." So ātma-darśanam means hṛdaya-granthi-bhedanam, opening the knot. Hṛdaya-granthi-bhedanam, that is ātma-darśanam. When I become free from all attachment of this material world, that is called hṛdaya-granthi-bhedanam.
And how the hṛdaya-granthi, knot in the heart, begins? That begins, puṁsaḥ striyā mithunī-bhāvam etat tayor mitho hṛdaya-granthim āhuḥ (SB 5.5.8). We are in this material world, it is going on, puṁsaḥ, the man, and striyā, of the woman, attachment. Puṁsaḥ striyā mithunī. What is that attachment? Sex. Sex. Puṁsaḥ striyā mithunī-bhāvam etat tayor. The desire is there, and as soon as they unite, by marriage or by agreement, by any way, then hṛdaya-granthim āhuḥ. Then the attachment becomes more and more. There are thousands and millions of woman, but the woman with whom I have got my bodily relation, I cannot forget her, and she cannot forget me. Hṛdaya-granthim āhuḥ. The attachment increases. And as soon as they are united, the..., that is hṛdaya-granthi, knot between heart to heart. "You my dear, you my heart." So then, "We must find out an apartment." There was no need of apartment, but as soon as there is hṛdaya-granthi, there is need of a...
