Bhagavad-Gita: Chapter 8, Verse 10

Rudra Vaisnava Sampradaya:

Visnuswami

Sridhara Swami's Commentary

One who is endowed with bhakti or loving devotion meditates with a steady mind on the Supreme Being. The reason for such sublime steadiness Lord Krishna is also stating that one having developed the power of yoga or the science of the individual consciousness attaining communion with the ultimate consciousness; and possessing the ability to raise the life force directly through the Sushumna channel fixing it between the eyebrows at the ajna-cakra or third eye a person attains the effulgently, resplendent Supreme Lord of all.

Brahma Vaisnava Sampradaya:

Madhvacarya

Madhvacarya's Commentary

The performance of beneficial activities at the time of death by those whose state of equanimity has achieved mastery of the life force and are able to direct it to the ajna cakra or the space between the eyebrows etc. is spoken now by Lord Krishna. Yet even for those who are bereft of mastery over the life force, true moksa or liberation from the cycle of birth and death comes about only through buddhi or spiritual intelligence, bhakti or loving devotion and vairagya or renunciation. So even in the absence of complete mastery on the strength of possessing equanimity from possessing buddhi, bhakti and vairagya liberation will be attained especially for the adepts.

In the Bhagavat Purana it is stated: Relishing the nectarian lilas or divine pastimes of the Supreme Lord, prompted by loving devotion to Him, those who are pure in heart have gained the wisdom of spiritual intelligence as a result of renunciation and also have attained the Supreme Lord, Himself in Vaikuntha, the eternal spiritual worlds. While others have through equanimity of mind succeeded with great effort in conquering the powerful impulses of material nature; those endowed with spiritual intelligence worship the Supreme Lord exclusively achieve dominance over material nature without any effort. The Moksa Dharma states: Those exalted beings who take exclusive shelter of the Supreme Lord, propitiating Him exclusively with fixed single minded attention attain Him, which far superior to any other endeavour. The Vyasa Yoga states: Through spiritual intelligence, loving devotion and renunciation moksa or liberation from the cycle of birth and death is assuredly available; but for those possessing equanimity of mind, moksa is expeditiously so.

Nimbaditya

Kesava Kasmiri's Commentary

One becoming full fledged in the power of yoga or the individual consciousness attaining communion with the ultimate consciousness in the form of concentration and meditation, possessing unending devotion, who at the time of death directs the life force through the sushana channel in the spinal cord and fixes it at the ajna chakra between the eyebrows, meditating with steadfast mind on the Supreme Lord Krishna most assuredly attains Him.
