SB 1.1 - The Lord is the shelter of all rasas
The Lord is rasa personified, which is confirmed in Taittirīya Upaniṣad (2.7): ‘raso vai saḥ’. The Bhāgavatam 10.43.17 also confirms that Kṛṣṇa is the form of all rasas combined because different types of people realized different rasas in Kṛṣṇa just on seeing Him. The jīva attains the highest level of bliss on attaining Kṛṣṇa. Other forms of the Lord also become filled with bliss on seeing Kṛṣṇa as confirmed in SB 10.89.58 and SB 3.2.12. Kṛṣṇa is rasa, the fruit, but this fruit is not directly situated on the tree of the Vedas. It has fallen down nearby. So the fruit is not to be searched out in the Vedas but rather it is found in the mouth of Śuka. The rasa is sweeter because of coming from the mouth of Śuka. The fully ripened fruit is rāgānuga-bhakti following after the sentiments of the gopīs. This is an acceptable meaning of the verse because it is said that the Vedas, taking up that type of bhakti, accepted the forms of hundreds of thousands of gopīs, and drank the sweet rasa of Kṛṣṇa’s lips.
The Lord is the shelter of Brahman too as explained in BG 14.27. It may be questioned how one can attain realization of Brahman, which has no qualities, by worshiping the Lord. To this Kṛṣṇa says that one can do it because He is the shelter of even the Brahman, which is famous in the śrutis as the shelter of everything. The Lord is the shelter of liberation (amṛtasya) because the word avyayasya indicates indestructible, which excludes the amṛta of the heavens. Kṛṣṇa is also the shelter of bhakti (dharmasya) which is continuous (śāśvatasya), being present as sādhana and as the result of sādhana (prema). He is the shelter of prema (aikāntikasya sukhasya), the goal of sādhana bhakti. Because everything is dependent on Him, one can merge into Brahman, by worshiping with such a desire.
