Srimad Bhagavad-Gita :
Chapter-10. ( Vibhuthi-yogam)
Slokam-11. ( Out of compassion for them, I, dwelling in their hearts, destroy with the shining lamp of knowledge the darkness born of ignorance.)
teshamevanukampartham ahamajnanajam tamah,
nasayamyatmabhavasthah jnanadipena bhasvata.
tesham anukampartham eva = certainly because of the sympathy / mercy / special consideration for them only;
aham atmabhavasthah = I am being in their Atma ( within themselves );
bhasvata jnanadipena = as glowing light of knowledge;
ajnanajam = ( their ) ignorance;
tama nasayamy = of darkness, ( I ) dispel / wipe out/ destroy/remove.
Sometimes philosophers criticize the devotees because they think that most of the devotees are in the darkness of ignorance and are philosophically naive sentimentalists.
Actually that is not the fact.
There are very, very learned scholars who have put forward the philosophy of devotion, but even if a devotee does not take advantage of their literature or of his spiritual master, if he is sincere in his devotional service he is helped by Lord Himself within his heart.
So the sincere devotee engaged in devotions cannot be without knowledge.
The only qualification is that one carry out devotional service in full Lord consciousness.
The modern philosophers think that without discriminating one cannot have pure knowledge.
For them this answer is given by the Supreme Lord: those who are engaged in pure devotional service, even though they be without sufficient education and even without sufficient knowledge of the Vedic principles, are still helped by the Supreme God, as stated in this slokam.
The Lord tells Arjuna that basically there is no possibility of understanding the Supreme Truth, the Absolute Truth, the Supreme Personality of Godhead, simply by speculating, for the Supreme Truth is so great that it is not possible to understand Him or to achieve Him simply by making a mental effort.
Man can go on speculating for several millions of years, and if he is not devoted, if he is not a lover of the Supreme Truth, he will never understand the Supreme Truth.
Only by devotional service is the Supreme Truth, Lord pleased, and by His inconceivable energy He can reveal Himself to the heart of the pure devotee.
The pure devotee always has Lord within his heart; therefore he is just like the sun that dissipates the darkness of ignorance.
This is the special mercy rendered to the pure devotee by the Lord.
Due to the contamination of material association, through many, many millions of births, one's heart is always covered with the dust of materialism, but when one engages in devotional service, the dust quickly clears, and one is elevated to the platform of pure knowledge.
The ultimate goal can be attained only by this devotional service, and not by mental speculation or argument.
The pure devotee does not have to worry about the necessities of life; he need not be anxious because when he removes the darkness from his heart, everything is provided automatically by the Supreme Lord, for He is pleased by the loving devotional service of the devotee.
This is the essence of the Gita's teachings.
By studying Bhagavad-gita, one can become a completely surrendered soul to the Supreme Lord and engage himself in pure devotional service.
As the Lord takes charge, one becomes completely free from all kinds of materialistic endeavors.
