Although karma, jnana and yoga are discussed in Bhagavad-gita, the only purpose is to inform us of Krishna’s greatness and engage us in His devotional service.

A.C. Bhaktivedanta Swami Prabhupada
Loving devotional service to the Lord begins with hearing about the Lord.
Srimad Bhagavatam 1.7.7,
Srila Prabhupada
Jayapataka Swami
When we expose ourselves to severe vaisnava-aparadha, it is like pulling our devotional creeper out from the root. It doesn't get the nourishment then we systematically dry out, then we lose the taste for chanting, reading, deity worship, book distribution, what could be worse! We lose devotional service ultimately.
Gopal Krishna Goswami Maharaj
Devotional service is so simple, but devotees because of their material inclinations make it complicated.
Lokanath Swami
Keep up your endeavor for engaging in devotional service. Chanting the Holy Names is a vital point of devotional service. Be sure to improve on your quality of chanting. All other services are strongly supported by chanting of the Holy Name.
Lord Shiva
In Vaikuntha nothing exists but devotional service, rendered through sankirtana and in many other forms. It goes on incessantly, with great enthusiasm spreading the ecstasy of pure love.
