Vaishnava Samhita. Purushottamadasa Charitam. Vol III Book VI Chp 24 Shlokas 27 - 29

परिपूर्णं करोत्येव भक्तानां काममच्युतः |
कामयन्ते कृष्णमेव निष्कामा वैष्णवाश्च ते ||
यः पठेत् साक्षिगोपालचरितं परमं शुभम् |
स प्राप्नोति परां भक्तिं श्रीकृष्णचरणाम्बुजे ||
भक्तिरेव महालाभो ब्रह्मादिसुरदुर्लभा |
तस्माद्भक्तिं विना नान्यं वरमिच्छन्ति वैष्णवाः ||  

Shri Bhagavan fulfils all the desires of His bhaktas. The devotees have all their selfless desires centering around Lord Krishna. True devotion to the Lord is the greatest of all attainments. It is not accessible even to the devas like Brahma. So, the vaishnavas do not cherish any boon other than true bhakti. Those who read the glorious story of Shri Sakshi Gopala attain loving devotion to the lotus feet of Lord Krishna

Thus ends Chapter Twenty Four entitled 'Purushottamadasa Charitam' of Book VI of Shri Vaishnava Samhita composed by Shri Shri Krishna Premi Swamigal.
