Bhagavad-Gita: Chapter 8, Verse 15

Rudra Vaisnava Sampradaya:

Visnuswami

Sridhara Swami's Commentary

Although the Lord Krishna is easily attainable by His devotees what does it mean? This is being answered here. The mahatmanah or great souls are His devotees and having attained Him they are released from samsara the perpetual cycle of birth and death having realised the purpose of human existence and reaching the highest perfection in Him are automatically granted moksa or liberation from the material existence and promotion to Vaikuntha the eternal spiritrual worlds.

Brahma Vaisnava Sampradaya:

Madhvacarya

Madhvacarya's Commentary

In this verse Lord Krishna praises that state of attainment itself. Attaining the Supreme Lord is solely the ultimate goal.

Sri Vaisnava Sampradaya:

Ramanuja

Ramanuja's Commentary

Those who attain Lord Krishna do not return to the impermanent material existence and temporary condition of samsara the perpetual cycle of birth and death the abode of misery and suffering. The devotees of Lord Krishna are mahatmas or great, noble souls who have enlightened themselves as to the real nature of His nama or name, rupa or form, guna or attributes, dhama or abode and lila or divine pastimes. Such exalted beings feel such fervid love for Him in separation that their very life becomes unsupportable. Those whose mind are focused on Him and whose heart is only for Him in bhakti or loving devotion is the very heart in which He resides. Those who by incessantly meditating upon Him will attain the highest perfection which is the Supreme Lord Krishna. Next will be discussed why the arthathi or seeker of wealth return to material existence and the bhaktas or the devotees of Lord Krishna are liberated from material existence.

Kumara Vaisnava Sampradaya:

Nimbaditya

Kesava Kasmiri's Commentary

Just as the Lord Krishna is easily attainable by His exclusive devotees; other gods must be easily attainable to their votaries as well and grant them all their desires objects. If this is the case what is the difference between Lord Krishna's devotees and the votaries of any other god? Lord Krishna answers this with the words mam upetya meaning having attained Him. Having attained the Supreme Lord what comes of it? The mahatmas or great souls are not subjected to rebirth ever again in the material existence for they have attained paramam samsiddhim the highest perfection. Because of their extraordinary discriminating powers such great, noble souls have correctly come to the ultimate conclusion that Lord Krishna is the ultimate goal for all living entities. Always thinking of Him, consciously performing all actions in propitiation to Him, having Him exclusively as their nearest and dearest, by the grace of the Supreme Lord who is eternal bliss personified one has qualified to join Him in His lilas or divine pastimes and eternally perform transcendental pastimes with Him in loving devotion. Attaining this automatically achieves moksa or liberation and released from the excruciating pangs of material existence beginning with 10 months of imprisonment in the womb of a mother then born in a house of sorrows known as the physical body and subjected to disease, old age and death again and again endlessly. No other god, gods or demigods can bequeath liberation from material existence except Lord Krishna and no other god, gods or demigods can sanction promotion to the eternal spiritual worlds except the Supreme Lord Krishna.
