Bhagavad-Gita: Chapter 7, Verse 11

Rudra Vaisnava Sampradaya:

Visnuswami

Sridhara Swami's Commentary

Rajas or passion is an active desire for things unattained. Attachment though is a passive emotion of the mind which incites the thirst for more of a desired object after already experiencing it. So when Lord Krishna states: kama-raga-vivarjitam meaning devoid of passion and attachment He is explaining the nature of His strength. He is the serene, sublime strength which empowers one to regularly perform their spiritual duties without deviation or cessation. He is also the passion which is never contrary to sanatan dharma or eternal righteousness and which is beneficial in marriage and having a son by one's wife.

Brahma Vaisnava Sampradaya:

Madhvacarya

Madhvacarya's Commentary

Being completely devoid of desires and attachments Lord Krishna is eternally full and powerful in strength. This is His natural propensity and contains no rajas or passion. Since He bestows strength similar to His like He did with the five Pandavas, He is balam balavatam or the strength of the strong. Since ba symbolises strength and la symbolises bliss, He is the bliss of strength Himself.

It is primarily the unchecked desires for sensual enjoyments that causes the diminution of piety and morality; but these desires are not detrimental if they are attuned to sanatan dharma or eternal righteousness. The Supreme Lord resides in all desires that are not contrary to sanatan dharma; but he never resides in any action that is contrary to righteousness. Therefore the Supreme Lord Krishna even while abiding in everything still has the capacity to remain distinct from them although as the Supreme Lord He encompasses all.

Sri Vaisnava Sampradaya:

Ramanuja

Ramanuja's Commentary

Lord Krishna declares that all these things of distinguishing qualities manifest from Himself only and not from any other. All things are His parts and parcels and constitute His body. Hence all things are always in Him and He is always in all things. He is the sole existing reality and all things are completely dependent upon Him. Next we will see things viewed in another way.

Kumara Vaisnava Sampradaya:

Nimbaditya

Kesava Kasmiri's Commentary

Lord Krishna continues explaining His subtle qualities that He is the strength of the mighty performing their individual duties devoid of passion and attachment. He is the energy of sexual desire for procreation which is not contrary to virtue and righteousness and does not conflict with the injunctions and prohibitions of the Vedic scriptures. Passion is the unabated craving to get a not yet obtained object with the thought to enjoy it. Attachment is the mental conditioning which after obtaining and enjoying an object makes one cling to the conception that such an object must always remain and continued to be enjoyed.
