Krishna Says

Chapter-9 Text-30
api chetsuduracharo bhajate maamananyabhak
sadhurev sa mantavyah samyagvyasito hi sah.
Translation: -
If even the most immoral person pays devotional service to me single mindedly, he should be considered a sage because he is properly situated in his determination.
Purport :-
People commonly judge a person by his outward behavior, they neither have will nor capacity to see his inner feelings and intentions.
They easily pass aspersions without thinking on even a righteous person when they see him doing one wrong action but when they see a man who is considered immoral, involved in paying devotion to God, they would call him a pretender. The people with dirty conscience further litter it with such talks. But the Supreme Lord is the ocean of pity and compassion. He considers only our inner feelings. He sets. His eyes upon a person's feelings and intentions and not upon his outward behaviors.
He is all-seeing and when he sees one with firm determination in one's mind that 'God is mine and I am God's,' engaged single mindedly in paying devotions to Him, He embraces him. He says that such a person must be considered a saint even if his conduct is not pure. It is not only a matter of consideration but also becomes true if he whole heartedly submits to God and chants His holy name. He is then purified of all his weaknesses and material contaminations.
Even in the life of an immoral person there may be some turning points when he may make him come to God with submission. Like when he is face to face with a crisis or he comes under the influence of a saint or a sage or he sees some miracle and is effected by that. Sage Valmiki and Ajamil are its brilliant examples. In spite of being immoral, by the grace of some saints they turned to God and this made them turn a new leaf in life. They were called saints and attained salvation as they had made chanting God's holy name their only duty and to attain oneness with God was their single aim. To attain name or fame, wealth or material comforts was not their aim.
The Supreme Lord says that "Though even a person is not entirely free from immorality, though he sometimes, compelled by situation or due to force of habit, commits mistakes and does something which can be considered abominable, yet God says that he should be considered a saint. One's he becomes a suppliant of God and says to Him that it is beyond his power to get over the weaknesses of his character and that it is possible only by His grace, the Ocean of Compassion, the Supreme Lord, Who looks after his devotee in all ways, purifies his conduct by pulling him over his weaknesses and passions and he becomes a true saint.
