All the devotees. So Narottama dāsa Ṭhākura says, "So all these associates of Caitanya Mahāprabhu should be known—they are also of the same category." Gaurāṅgera saṅgi-gaṇe, nitya-siddha kori māne. This word nitya-siddha is significant. Nitya-siddha and nitya-baddha. There are two kinds of living entities. Nitya-baddha means ever-conditioned. Ever-conditioned means those who are in this material world, they do not know when they came in touch with this material world. Neither they do know when they will be liberated. They are called nitya-baddha, ever-conditioned. And similarly, there are nitya-siddhas. Nitya-siddhas means they never come in contact with this material world, and even they come here for some business, they do not forget their position. That is nitya-siddha. Try to understand. There are two kinds of living entities: nitya-siddha, nitya-baddha. Nitya-baddhas are within this material world. Beginning from Brahmā down to a small ant, insignificant ant, they are all nitya-baddhas. Anyone who is in this material world—nitya-baddha. And nitya-siddhas, they belong to the spiritual world. They never come in contact with this material world, and even they come for some business under the order of the Supreme Lord, they do not touch these material qualities They remain always transcendental. As Kṛṣṇa remains always transcendental, even though He is in this material world, similarly, Kṛṣṇa's nitya-siddha associates, they are also transcendental. They never touch this material world.
(Lecture on Bhagavad-Gita----1:13-14).

Nitya-baddha. This word is also technical. Nitya-baddha means ever-conditioned. There are nitya-muktas. Nitya-mukta means ever-liberated. In the spiritual world, there are also innumerable living entities. The... This material world is only one-fourth manifestation of Kṛṣṇa's energy, God's energy. And the three-fourths energy is manifested in the spiritual world. So we can just imagine that in one-fourth manifestation of energy of the Lord, we are so many living entities which is impossible to count. Now you can imagine how many more living entities are there. But here we are conditioned and they are liberated. Those who are conditioned, they are called nitya-baddha, ever-conditioned. Nitya-baddha means we do not know when our, this conditional stage has begun. It is impossible to trace out the history. But we are conditioned. There is no doubt about it. Conditioned means no freedom. No freedom. As spirit soul we are free. Sarva-ga, we can go everywhere, anywhere. Even those who get some mystic powers by perfection of yoga practice, they can also exhibit some powers. So why? As we become free from material conditions, our original freedom comes.
(Lecture on Srimad Bhagavatam----1:3:1-3).

Kṛṣṇa says, mamaivāṁśo jīva-bhūtaḥ: (B.G.15:7) "All living entities, they are My part and parcel." Ahaṁ bīja-pradaḥ pitā: (B.G.14:4) "I am the seed-giving father." So how this relation can be broken? That is not possible. That is already there eternally.
Therefore it is said in the Caitanya-caritāmṛta, nitya-siddha kṛṣṇa-bhakti. Nitya-siddha means eternally perfect. It is not that we are artificially acquiring this kṛṣṇa-bhakti. No, it is not artificial. It is natural. This is actual fact. So we are simply... Because our present, in the present material condition, our heart is covered with so much garbage of different types of body... Just like all of a sudden something comes to your mind. It has no connection. Just like a bubble, comes out. Because so many dirty things are reserved on account of our material conditional life for millions and millions of years. Anādi karama-phale paḍi' bhavārṇava-jale. Anādi, we cannot... Anādi means... Ādi means the creation. So before this creation. Bhūtvā bhūtvā pralīyate (B.G.8:19). We are in this material contamination not that in this millennium-before that. Just like millennium after millennium. Nārada Muni was speaking his life before this millennium. So anādi. Anādi means creation. But not only one creation, several creations, we are forgotten, or we are in this material world. Kṛṣṇa-bahirmukha hañā bhoga vāñchā... We are searching after material comfort, material comfort, sense gratification, in so many ways. So anādi karama-phale paḍi' bhavārṇava-jale, taribāre nā dekhi upāya. In this way we are going.
(Lecture on Bhagavad-Gita---7:2).

So this is the difference between sādhana-siddha and nitya-siddha. Gaurāṅgera saṅgi-gaṇe, nitya-siddha kari' māne, se yāya vrajendra-suta-pāśa. Gauḍa-maṇḍala-bhūmi, yebā jāne cintāmaṇi, tāra haya vrajabhūme vāsa. So nitya-siddha means he has no chance to forget Kṛṣṇa. That is called nitya-siddha. And sādhana-siddha means by following the regulative principles, the rules and regulations, one revives his Kṛṣṇa consciousness. Both things are siddha because you cannot revive Kṛṣṇa consciousness without being Kṛṣṇa conscious. It may be covered. So nitya-siddha means he does not get covered by the influence of material nature about his natural devotional tendency to serve Kṛṣṇa. He never becomes covered. This is difference. Kṛṣṇa gives him chance to get birth in such a family. Just like Parīkṣit Mahārāja, that he never gets the chance of forgetting Kṛṣṇa. So one who does not get the chance of forgetting Kṛṣṇa is called nitya-siddha. This is the difference.
