The Shikshashtakam (IAST: Śikṣāṣṭakam) is a 16th-century Gaudiya Vaishnava Hindu prayer of eight verses composed in the Sanskrit language. They are the only verses left personally written by Chaitanya Mahaprabhu (1486 – 1534) with the majority of his philosophy being codified by his primary disciples, known as the Six Goswamis of Vrindavan. The Shikshashtakam is quoted within the Chaitanya Charitamrita, Krishnadasa Kaviraja Goswami's biography of Chaitanya Mahaprabhu, written in Bengali. The name of the prayer comes from the Sanskrit words Śikṣā, meaning 'instruction', and aṣṭaka, meaning 'consisting of eight parts', i.e., stanzas. The teachings contained within the eight verses are believed to contain the essence of all teachings on Bhakti yoga within the Gaudiya tradition.
The first eight verses of the following are the complete text of the Shikshashtakam, as written in Sanskrit by Sri Chaitanya Mahaprabhu. They are found in Krishnadasa Kaviraja's Sri Chaitanya Charitamrita (Antya-līlā, chapter 20, verses 12, 16, 21, 29, 32, 36, 39 and 47). The final verse is a Bengali quotation from Sri Chaitanya Charitamrita, Antya-līlā 20.65 - it is not part of the actual Shikshashtakam, but is often appended to the end when it is recited, describing the result of reciting the Shikshashtakam faithfully.
ānandāmbudhi-vardhanaḿ prati-padaṁ pūrṇāmṛtāsvādanaṁ
sarvātma-snapanaṁ paraṁ vijayate śrī-kṛṣṇa-saṅkīrtanam
आनन्दाम्बुधि-वर्धनं प्रति-पदं पूर्णामृतास्वादनं
सर्वात्म-स्नपनं परं विजयते श्री-कृष्ण-सण्कीर्तनम्
Glory to the Shri Krishna sankirtana (congregational chanting of the Lord's holy names), which cleanses the heart of all the dust accumulated for years and extinguishes the fire of conditional life, of repeated birth and death. That sankirtana movement is the prime benediction for humanity at large because it spreads the rays of the benediction moon. It is the life of all transcendental knowledge. It increases the ocean of transcendental bliss, and it enables us to fully taste the nectar for which we are always anxious.
nāmnām akāri bahudhā nija-sarva-śaktis
tatrārpitā niyamitaḥ smaraṇe na kālaḥ
etādṛśī tava kṛpā bhagavan mamāpi
durdaivam īdṛśam ihājani nānurāgaḥ
नाम्नामकारि बहुधा निज-सर्व-शक्तिस्
तत्रार्पिता नियमितः स्मरणे न कालः एतादृशी तव कृपा भगवन्ममापि
दुर्दैवमीदृशमिहाजनि नानुरागः ॥२॥
Literal: In your (divine) names manifested various kinds of full potencies (shaktis) therein bestowed, with no rules according to time for remembering them, O Lord, you are so merciful, but it is my misfortune here that I have no anuraga (interest) in those names.
tṛṇād api sunīcena
taror iva sahiṣṇunā

तरोरऽपि सहिष्णुना अमानिना मानदेन
कीर्तनीयः सदा हरिः ॥३॥
By considering (self) lower than straw, more tolerant than a tree, giving honour to those devoid honour, always do kirtana of hari.

No wealth, no followers, no beauty or poetic praise desire I; in birth after birth let there be devotion unmotived unto thee o ishvara.
O Lord of the Universe, I do not desire wealth, followers, beautiful women, nor the flowery language of the vedas; let me have only causeless devotion to you, birth after birth.

o son of nanda, servitor me fallen in venom of ocean of material existence, by your mercy (kripa) consider me as particle of dust at your lotus-feet.

With eyes flowing tear-streams, voice faltering, words choked, with ecstatic feelings in body, when shall i be able to chant thy (divine) name?

by embracing with enraptment or trampling with feet, or breaking my heart by not granting vision, or flirting here and there as destined, master of my life is he, verily no other.
This verse follows the 8 verses written by Chaitanya in Śrī Caitanya-caritāmṛta:
prabhura ‘śikṣāṣṭaka’-śloka yei paḍe, śune kṛṣṇe prema-bhakti tāra bāḍe dine-dine
If anyone recites or hears these eight verses of instruction by Śrī Caitanya Mahāprabhu, their ecstatic love and devotion (prema-bhakti) for Kṛṣṇa increases day by day.

He requested a select few among his followers, who later came to be known as the Six Goswamis of Vrindavan, to systematically present in their writings the theology of bhakti he had taught."
