This book is not meant for the faithless materialist. Only those who have developed unflinching faith in Lord Caitanya and in the process of chanting the holy name are eligible candidates to hear the topics discussed in this book. Amongst the different levels of sādhana-bhakti, he who is convinced that all perfections are obtained by chanting the holy name alone is the topmost sādhaka or practitioner. Lord Caitanya has personally instructed this lesson in His Śrī Śikśāṣṭaka. He ordained Śrīla Haridāsa Ṭhākura as the nāmācārya or spiritual authority on the subject of chanting the holy name of the Lord.
Śrīla Bhaktivinod Ṭhākur is a great Vaiṣṇava ācārya in the Gauḍīya (Bengali) line. He is also known as the 'seventh Gosvāmī' because of his deep realization of rasa and preaching.
