Prabhupader Catur-grantha Gita
arjunera duhkha haite, ashtadasadhyaya madhye
sarva-dharma-vidhi-tyaga, krishna-vancha mukhya anga
krishna-bhakti ei sreshtha upaya
The Bhagavad-gita is an ocean of Lord Krishna's nectarean words, spoken (lit: obtainable) in eighteen chapters to assuage Arjuna's lamentation. Giving up the strictures of all (other) principles of religion, (one should accept the Gita's) central principle: (to serve) Krishna's desire. Devotion to Krishna is the ultimate means (of spiritual success).
vyasadever grantha-varya, prasiddha sri-bhagavata
suniya ei krishna-katha, prema-bhakti upajaya
hridoy bahir rahe soka-moha
The famous Srimad-Bhagavatam is Srila Vyasadeva's most excellent work, the essence of all topmost scriptures. (In the heart of one who) hears its narrations about Krishna, pure loving devotion arises, as lamentation and illusion remain far away from the heart.
krishnadaser param kavya, caitanyera itihasa
gaurangera tattva jane, daser anudasa-bhave
suddha-bhakti habe sarva-loke
Krishnadasa Kaviraja's sublime work of poetry describing the history of Caitanya Mahaprabhu is a mine (of inspiration) for the Vaishnavas of the Gaudiya tradition. (By reading it) one comes to know the truth of Gauranga and attains the mood of being a servant of the servant; thus pure bhakti comes about for everyone.
rup-gosaier rasa-grantha, rasera viveka-pantha
vidhi, raga, bhava, prema, krame sab vistara-katha
tabe bhakter hridoya ujjvala
Rupa Gosvamis relishable work of the name Bhakti-rasamrita-sindhu shows the way to carefully analyze devotional mellows. It is an expanded progressive explanation of devotion in the stages of regulation, attachment, intense devotion, and pure love. The hearts of the devotees who read it become illuminated.
