CC Madhya 24.109
- bhakti vinā kevala jñāne 'mukti' nāhi haya
- bhakti sādhana kare yei 'prāpta-brahma-laya'
bhakti—devotional service; vinā—without; kevala—only; jñāne—by philosophical speculation; mukti—liberation; nāhi haya—there is not; bhakti—devotional service; sādhana—practice; kare—does; yei—anyone who; prāpta-brahma-laya—as good as merging into the impersonal Brahman.
"One cannot attain liberation simply through philosophical speculation devoid of devotional service. However, if one renders devotional service, he is automatically on the Brahman platform.
