Bhagavad-Gita: Chapter 10, Verse 9

Rudra Vaisnava Sampradaya:

Visnuswami

Sridhara Swami's Commentary

The worship being explained here is bhakti or exclusive loving devotion. The words mac-citta means those who hearts are dedicated unto the Supreme Lord alone. Whose mind and senses are also totally directed to Him solely. The word mad-gatah-pranah means those who have dedicated their lives to the Supreme Lord Krishna. Such spiritually intelligent beings reflect upon His phenomenal glories, incessantly relishing His lilas or divine pastimes and enlightening each other of their reflections and experiences in their internal mood of loving devotion to Him and enjoy sublime, transcendental bliss.

Brahma Vaisnava Sampradaya:

Madhvacarya

Madhvacarya's Commentary

The words mad-gata-prana means that one surrenders their very life to Lord Krishna, meaning that all their thoughts and actions are directed for His satisfaction exclusively.

Sri Vaisnava Sampradaya:

Ramanuja

Ramanuja's Commentary

The words mac-citta means those who devote their hearts on Lord Krishna. The words mad-gata-prana means those whose lives cannot exist without Lord Krishna. Such great beings constantly enlighten each other about His transcendental attributes and extraordinary lila's or divine pastimes and exchange bliss by relating the realisations they have experienced from such. The sense of satisfaction from the mere conversation about Lord Krishna makes them so blissful that there contentment is permanent and needs nothing else to complete it. Furthermore simply hearing about Lord Krishna's lila's causes these devotees to become ecstatic, exhibiting a rapturous and exultant glow of love.

Kumara Vaisnava Sampradaya:

Nimbaditya

Kesava Kasmiri's Commentary

Here Lord Krishna elaborates on the great souls method of worship with the words mac-citta or their minds dedicated to Him and mad-gata-prana or their life airs surrendered fully to Him inferring also the presiding demigods and their function over their respective sense organs such as ear and eye, etc. This denotes using the eyes to see the Supreme Lord, using the ear to hear His praises, using the tongue to chant His glories, etc. all for propitiating Him as the goal. Enlightening one another about their realisations about Him, exchanging ecstasies with each other about their realisations and experiences with Him. Also discoursing with the appropriates logical and introspective reasoning propounded in the Vedic scriptures and the commentaries of the previous acarya's in disciplic succession about Lord Krishna's supreme absolute position as the sole cause, maintainer and sustainer of all creation. Of one mind and heart discussing His transcendental qualities and attributes they grow in true friendship and admiration for each other relating whatever knowledge they have of Him, great or small it is all mutually relished whether they speak of His virtues, His mercy, His avatars or incarnations or His phenomenal extraordinary lila's or divine pastimes or just by hearing about them. From both a wonderful feeling of indescribable contentment arises and they become completely satisfied within.
