There are TEN such predictions available in Vedic scriptures on  the advent of Lord Chaitanya Mahaprabhu none other than Lord Krishna himself.

 

1. First Prediction : Srimad-bhagavatam ( 11.5.32)

krishna-varnam tvishakrishnam sangopangastra-parshadam

yajnaih sankirtana-prayair yajanti hi sumedhasah

In the age of Kali, intelligent persons perform congregational chanting to worship the incarnation of Godhead who constantly sings the holy name of Krishna. Although His complexion is not blackish, He is Krishna Himself. He is accompanied by His associates, servants, weapons and confidential companions.

krsna-varnam: This word denotes that Lord Chaitanya belongs to the category of Krishna or in other words He is Krishna Himself. krsna-varnam also means one who constantly chants the name of Lord Krishna.

tvisa akrsnam: His bodily complexion is not black. He appeared in golden-like yellow complexion.

sangopangastra-parsadam: Lord Chaitanya is always accompanied by His confidential associates like Lord Nityananda, Advaita Acharya, Sri Gadadhara Pandita, Srivasa Acharya, Haridasa Thakura, etc. In other incarnations, the Lord sometimes made use of His weapons to defeat or kill the demons, but in this age the Lord subdues the demonic mentality with His all-attractive figure of Chaitanya Mahaprabhu who freely distributes Krishna-prema, pure love of Krishna. That is His weapon.

2. Second Prediction: Vishnu-sahasra-nama stotra from Mahabharata

Each of the 1000 names contained in the Vishnu-sahasra-nama stotra that is found in the Mahabharata, glorifies one or more aspects of the Supreme Lord’s transcendental forms, qualities, pastimes etc.

The following names indicate the bodily features of Lord Chaitanya.

suvarna-varno hemango varangas candanangadi

suvarna-varna: He has a golden complexion.

hemanga: He has the appearance of molten gold.

varanga: He is exquisitely beautiful.

candanangadi: The Lord’s body is smeared with sandalwood pulp.

Lord Chaitanya’s qualities and activities are described in the following names.

sannyasa-krc chamah santo nistha-santi-parayanah

sannyasa-krt: He accepts the renounced order of life. (Lord Chaitanya accepted sannyasa at the age of 24.)

sama: He is fully sense-controlled or equipoised.

santa: He is completely peaceful.

nistha: He is rigidly fixed in the chanting of the holy name of Lord Krishna.

santi-parayana: He is the highest abode of devotion and peace. He silences the impersonalist philosophers. (Lord Chaitanya defeated many eminent mayavadis in philosophical debates and converted them to Vaishnavism.)

3. 3rd Prediction of Chaitanya Mahaprabhu: Garuda Purana

The Supreme Lord says,

aham purno bhavisyami yuga-sandhyau visesatah

mayapure navadvipe bhavisyami saci-sutah

In the first part of Kali-yuga, I will appear in my complete spiritual form in Mayapura, Navadvipa and become the son of Shachi. 

Sri Chaitanya was born in Mayapura (a subsection of the holy town of Navadvipa, West Bengal) as the son of Srimati Shachi devi in the year 1486, about 4,500 years after the beginning of the Kali-yuga.

It is also stated in this purana,

kaleh prathama-sandhyayam laksmi-kanto bhavisyati

daru-brahma-samipa-sthah sannyasi gaura-vigrahah

In the first part of Kali-yuga, the Supreme Lord in the golden complexion will become the husband of Lakshmi. Then He will become a sannyasi and reside near Lord Jagannatha.

Sri Chaitanya married His eternal consort Srimati Lakshmipriya and later took sannyasa at the age of 24. After the acceptance of sannyasa, He left Navadvipa and resided in Puri, the holy city of Lord Jagannatha in Orissa. Lord Jagannatha in Puri is also referred to as daru-brahma in the Puranas as the Deities here are made from Neem wood. The word daru means wood in Sanskrit.

yo reme saha-ballavi ramayate vrndavane ‘har-nisam

yah kamsam ni jaghana kaurava-rane yah pandavanam sakha

so ‘yam vainava-danda-mandita-bhujah sannyasa-vesah svayam

nihsandeham upagatah ksiti-tale caitanya-rupah prabhuh

The Supreme Lord who took delight in His pastimes with the gopis, who filled the residents of Vrindavana with joy day and night, who slew Kamsa, and who made friends with the Pandavas in the battle between the Kauravas, will without any doubt, come again to the earth. He will be a sannyasi with the name Chaitanya whose arm will be decorated with a bamboo stick.

It is clear from this verse that Lord Krishna Himself appeared as Chaitanya Mahaprabhu. According to the custom, a sannyasi is supposed to carry a bamboo stick (danda). Lord Chaitanya carried a single bamboo stick as He was an eka-danda sannyasi.

4. Fourth Prediction of Chaitanya mahaprabhu :Nrsimha Purana

satye daitya-kuladhi-nasa-samaye

simhordhva-martyakrtis

tretayam dasa-kandharam

paribhavan rameti namakrtih

 

gopalan paripalayan vraja-pure

bharam haran dvapare

gaurangah priya-kirtanah

kali-yuge caitanya-nama-prabhuh

 

The Supreme Lord who assumed the form of a half-man, half-lion in the Satya-yuga to cure a dreadful disease that had devastated the Daityas, and who appearing as Rama conquered the ten-headed Ravana in the Treta-yuga, and who removed the burden of the earth in the Dvapara-yuga and protected the cowherd men of Vraja-pura, will be the Lord by name Chaitanya in the Kali-yuga. He will have a golden form and He will take pleasure in chanting the Lord’s holy names

bhagirathi-tate ramie bhavisyami saci-sutah

I shall take birth as the son of Shachi assuming a golden form in a beautiful place on the bank of the Bhagirathi (Ganges) on the earth in the first part of Kali-yuga.

Mayapura, the birth place of Sri Chaitanya is on the banks of the Ganges. There is a similar verse in the Brahma Purana predicting the appearance of Lord Chaitanya.

6. Sixth Prediction of Lord Chaitanya, Narada Purana

The Supreme Personality of Godhead says,

aham eva kalau vipra nityam pracchanna-vigrahah

bhagavad-bhakta-rupena lokan raksami sarvada

O brahmana, I will deliver all the worlds, concealing myself in the form of a devotee of the Lord in Kali-yuga.

divija bhuvi jayadhvam jayadhvam bhakta-rupinah

kalau sankirtanarambhe bhavisyami saci-sutah

O demigods, please advent on the earth as devotees in Kali-yuga. To inaugurate sankirtana, I will incarnate as the son of Shachi.

7. Seventh Prediction of Lord Chaitanya, Bhavishya Purana

The Supreme Lord states:

anandasru-kala-roma-harsa-purnam tapo-dhana

sarve mama eva draksyanti kalau sannyasa-rupinam

O austere sage, everyone will see My transcendental form as a sannyasi in the age of Kali. I will be displaying symptoms like shedding tears of bliss and hairs standing on end out of ecstasy.

Lord Chaitanya was always merged in the ocean of transcendental ecstasy while chanting the names of Krishna and dancing during sankirtana. He felt intense separation from the Lord and due to those devotional feelings displayed various ecstatic symptoms of pure love for Krishna, such as incessant tears, voice choking up, hairs on the body standing on end etc. 

8. Eighth Prediction of Lord Chaintaya, Vayu Purana

The Supreme Lord says,

paurnamasyam phalgunasya phalguni-rksa-yogatah

bhavisye gaura-rupena saci-garbhe purandarat

On the full moon day of the month of Phalguna, conjoined with the star Phalguni, I will appear in a golden form begotten by Purandara in the womb of Shachi.

Lord Chaitanya was born on the full moon day in the month of Phalguna. His father was known by the names Jagannatha Mishra and Purandara Mishra.

svarnadi-tiram asthaya navadvipe janasraye

tatra dvija-kulam prapto bhavisyami janalaye 

I will appear in a brahmana family in Navadvipa, by the shore of the Ganges.

bhakti-yoga-pradanaya lokasyanugrahaya ca

sannyasa-rupam asthaya krsna-caitanya-nama-dhrk

In order to engage the people in devotional service and bestow mercy upon them, I will take sannyasa, accepting the name Krishna Chaitanya.

9. Nineth Prediction of Lord Chaitanya : Matsya Purana

The following statement is made by the Lord:

mundo gaurah su-dirghangas tri-srotas-tira-sambhavah

dayaluh kirtana-grahi bhavisyami kalau yuge

In the age of Kali, I will be golden colour. I will be tall and will have a shaven head. The place where I take birth will be a meeting point of three rivers. I will be very merciful and I will keenly engage in chanting the holy names.

Lord Chaitanya, being an eka-danda sannyasi had a completely shaven head as was the custom for such sannyasis. Three rivers – the Ganges, the Yamuna and the Saraswati (which is currently in her hidden form) – flow at Navadvipa.

10. Tenth Prediction of Lord Chaitanya: Skanda Purana

The Supreme Lord states

antah krsnah bahir gaurah sangopangastra-parsadah
