BG Chap 18 - The box of secret treasure of bhakti

Seeing Arjuna silently reviewing the deep meaning of the Gītā, the Lord, His heart melting like butter due to mercy, said he would speak again the essence of the whole scripture. Kṛṣṇa said that since Arjuna is very dear to Him, and had faith in His authority, He would speak again the most confidential knowledge for Arjuna’s benefit. Kṛṣṇa said He would speak again because He had already said the same thing at the end of the ninth chapter. There Kṛṣṇa had asked Arjuna to think of Him always, become His devotee, worship Him and pay respects. These were the highest words, the most secret, the essence of the Gītā, which is the essence of the meaning of all scriptures. There is no secret greater than this anywhere. And Kṛṣṇa spoke this confidential topic to Arjuna because Arjuna was His dear friend, and without having such friendship, no one would speak anything confidential.

The three groups of six chapters of the Gītā are the box containing the most valuable secret treasure of bhakti. The first six chapters concerning karma are the lower covering made of gold. The last six chapters concerning jñana form the gem studded cover of the box. Within the middle six chapters resting within the container and the lid, shines the most excellent jewel of bhakti, which brings Kṛṣṇa under control. Bhakti’s servants consisting of two verses (BG 18.65 and 66) of sixty-four syllables placed on the lid of the box, is the key to obtain the priceless jewel.
