You know all these definition of bhakti given in our Nectar of Devotion. So spiritual life means free from material desires. And material desires mean just to hanker after sense gratification. This is material desire. When we have no more desire for sense gratification, then we should think that we are on the spiritual platform.
So this description of Vṛndāvana is spiritually described; therefore in the beginning the word is used, dīvyad. Dīvyad means divine. Kṛṣṇa says, janma karma ca me divyam (BG 4.9). This is not ordinary material thing. So desire tree also described in the Brahma-saṁhitā: cintāmaṇi-prakara-sadmasu kalpa-vṛkṣa (Bs. 5.29)—the same kalpa-vṛkṣa—lakṣāvṛteṣu surabhīr abhipālayantam, lakṣmī-sahasra-śata-sambhrama-sevyamānam. This lakṣmī-sahasra-śata-sevyamānam is described here as preṣṭhālībhiḥ sevyamānau. Preṣṭha-alībhiḥ. Preṣṭha means very dear, and alī means gopīs, associates of Rādhārāṇī, friends. So they are all Lakṣmīs, goddess of fortune. Lakṣmī. . . You have heard the name Lakṣmī, Lakṣmī-Nārāyaṇa, associates of Nārāyaṇa. Kṛṣṇa is Nārāyaṇa. So all these gopīs, they are expansion of Śrīmatī Rādhārāṇī, the original Lakṣmī. This is spiritual world. It is not impersonal, neither nirākāra, formless. Everything form, but that form is different from this form. That form is sat-cid-ānanda form—eternal, full of bliss, full of knowledge. This is not this material form. When we speak of formless, that means without any material form. Formless does not mean Kṛṣṇa and His expansion, they are formless. They are not of material form. Aprakṛta, not material. Here everything is prakṛta. It is not. . . neither eternal nor blissful nor full of knowledge. It is temporary, full of ignorance and always miserable, this form. We can understand it.
So that is just opposite. This form is temporary. Everyone knows this form will be finished. Antavanta ime dehā (BG 2.18), Kṛṣṇa says. This body is antavat. Antavat means it will be finished. It grew at a certain date, and it will increase, it will stay, then it will dwindle, then it will produce some by-products and then vanish. This is called ṣaḍ-vikāra, six kinds of changes of the material body. Of the spiritual body there is no such change. That is the difference between spiritual body and material body. Therefore it is called sat. Sat means eternal; there is no change. Just like Kṛṣṇa. His body is sac-cid-ānanda; therefore He never grows old. You'll never find a picture of Kṛṣṇa that He has grown old. No. There is no change. Advaitam acyutam anādim ananta-rūpam ādyaṁ purāṇa-puruṣam (Bs. 5.33). Purāṇa-puruṣam means the oldest person. Because Kṛṣṇa is the origin of everything. . . Sometimes they consider, "Because God is very old, therefore He must have big, big beard and. . ." That is imagination. Here you find the real description of God: advaitam acyutam anādim ananta-rūpam ādyam (Bs. 5.33), "Original," purāṇa-puruṣam, "the oldest of all," nava-yauvanaṁ ca, "but His bodily feature is just like a fresh young man." That is Kṛṣṇa. You'll never find Kṛṣṇa. . . Kṛṣṇa, when He was in the battlefield of Kurukṣetra, He was a great-grandfather, but you'll find a young boy. That is Kṛṣṇa. So that is eternal.
Now our body is not sat. Kṛṣṇa's body is sat, cid, ānanda. Our this material body—asat. And because we have got. . . Asat means temporary, that will not exist. And because we have accepted this material body, therefore we are full of anxiety. Ultimately, what is our anxiety? We are always trying to. . . This is called struggle for existence, survival of the fittest. So we are trying to become the fittest, to exist. But that is not possible in this body. That is not possible, because it is asat; it is not sat. And because the struggle is that we want to exist in this body, therefore there is anxiety. Asad-grahāt. Sadā samudvigna-dhiyām asad-grahāt (SB 7.5.5). The śāstra says that we are always full of anxieties. Why? Now, asad-grahāt: "We have accepted this body, which will not exist." Asad-grahāt. These are facts. Study śāstra in that way. Why we are full of anxiety? Because we have accepted this body.
