Bhagavad-Gita: Chapter 12, Verse 6,7

Rudra Vaisnava Sampradaya:

Visnuswami

Sridhara Swami's Commentary

Being so requested the Supreme Lord Krishna continues to reveal that unlike the path of the abstract, unmanifest, impersonalists which is dukham or miserable; His devotees are quickly delivered from mrtyu-samsara-sagarat or the deadly, never ending cycle of birth and death in the material existence and they attain atma-tattva or soul realisation by His grace. Those who mayi sannyasya mat-parah or dedicate all their activities to Lord Krishna and mayy avesita-cetasam or whose hearts are absorbed in thinking of Him without ananyenaiva or motives of exploitation and remuneration and who are surrendered in yogena or bhakti yoga exclusive in loving devotion are Lord Krishna's true devotees who have no other goal or object of attention then Him and He personally delivers them from the endless, revolving cycle of transmigration promoting them to the eternal spiritual worlds.

Sri Vaisnava Sampradaya:

Ramanuja

Ramanuja's Commentary

Actions are of two types. One is worldly activities undertaken to maintain and progress the material existence of the physical body such as obtaining food and shelter and material development. The other is spiritual activities enjoined by the injunctions of the Vedic scriptures such as propitiation to the Supreme Lord, absence of violence to any living being, charity, etc. in short every act without an ulterior motive and without a hopeful gain. Whosoever being spiritual minded without any motive except for satisfying the Supreme Lord Krishna and without any desire of seeking anything in return from Him, who offer all their activities as devotion to Him, keeping Him alone as their sole goal and in one-pointed devotion focus their meditation on Him fully while worshipping Him in all their activities such as chanting His holy names, glorifying Him, offering prayers to Him, prostrating before His deity form, hearing about His lilas or divine pastimes, enlightening others about His glories, etc. as the be all and end all of all existence itself. To such devotees as these who always are in communion with Lord Krishna in their hearts and minds, He Himself personally becomes their saviour by being their samuddharta or deliverer from mrtyu-samsara-sagarat or the deadly ocean of the perpetual cycle of birth and death which is the principle barrier which stops the atma's or eternal souls of all jivas or embodied from attaining Him when the end of each physical life has transpired.

Kumara Vaisnava Sampradaya:

Nimbaditya

Kesava Kasmiri's Commentary

The devotees of the Supreme Lord Krishna do not have to undergo any tribulations or difficulties in order to reach Him quickly. This is what He confirms in these two verses beginning with the words ye tu meaning but those who denotes those whose parents were conscious of Lord Krishna at the time of the infants very conception by which receiving such grace they were born devotees of the Supreme Lord or by destiny or karma being actions awarded based on previous actions, such beings acquire association of a pure devotee of Lord Krishna and are blessed by them. Such fortunate jivas or embodied beings depend exclusively upon the Supreme Lord because He is absolutely the ultimate goal to be attained above all others in every situation and in all circumstances. Such blessed beings are fully surrendered to the Supreme Lord, devoting their very lives for His complete satisfaction without motive or thought of recompense and reward for their activities. Even while engaged in worldly activities for preservation of bodily maintenance for self and family such as food and shelter as well as performing Vedically ordained activities according to varnasrama or the four social order of Vedic society such as propitiation to the Supreme Lord, charity, etc. such surrendered beings continuously remember Lord Krishna as their most beloved and single object of adoration, reflecting again and again incessantly over His rupa or divine form, His guna or divine qualities, His lilas or divine pastimes, His dhama or divine abode and madhurya or His divine transcendental sweetness. For such great souls Lord Krishna declares that He Himself becomes their saviour and personally delivers them from mrtyu-samsara-sagarat or the deadly ocean of the perpetual cycle of birth and death and this He declares that He does na cirat meaning without delay.

The conclusion is that by continuously offering their hearts and minds in uninterrupted bhakti or exclusive loving devotion to the Supreme Lord Krishna, He becomes indebted to them so much so that He personally goes and rescues them from samsara, the perpetual cycle of birth and death and promotes them to the immortal spiritual worlds to eternally share in exclusive blissful communion with Him
