For the pure devotee of the Lord there is nothing beyond the lotus feet of the Lord, and the Lord knows that such devotees do not wish anything more than that. The word tu specifically establishes this fact. The Lord also does not wish to be separated from the lotus hearts of those pure devotees. That is the transcendental relationship between the pure devotees and the Personality of Godhead. Because the Lord does not wish to separate Himself from the hearts of such pure devotees, it is understood that they are specifically dearer than the impersonalists. The relationship of the pure devotees with the Lord develops because of devotional service to the Lord on the authentic basis of Vedic authority. Such pure devotees are not mundane sentimentalists, but are factually realists because their activities are supported by the Vedic authorities who have given aural reception to the facts mentioned in the Vedic literatures.
The word parayā is very significant. Parā bhakti, or spontaneous love of God, is the basis of an intimate relationship with the Lord. This highest stage of relationship with the Lord can be attained simply by hearing about Him (His name, form, quality, etc.) from authentic sources like Bhagavad-gītā and Śrīmad-Bhāgavatam, recited by pure, unalloyed devotees of the Lord.
