Srimad Bhagavad-Gita :
Chapter-12. ( Bhakti-yogam )
The words avesya manah means focusing the mind and includes fixing the heart exclusively upon Lord Krishna otherwise if it is not exclusive something else may enter in and then it will not be possible for the Supreme Lord to be their only object of meditation. The word sraddha means firm faith and those so endowed eagerly and enthusiastically strive for divine communion with the Supreme Lord.
Those who propitiate Lord Krishna in this way with mind and hearts absorbed totally in Him are His best devotees and yuktamamah the most superior of all as they joyfully and skilfully with great eclat and determination navigate themselves swiftly through the currents of life to attain eternal communion with the Supreme Lord.
Lord Krishna confirms that those who with firm faith focus their consciousness exclusively upon Him without cessation are yuktatamah or the most superior of all as they worship Him, who is an ocean of divine attributes and qualities such as omniscience, omnipotence, compassionate, noble, etc. continuously within their minds which by contemplating eradicates any blemishes and imperfections such devotee may still possess.
In response to the question from verse one the Supreme Lord Krishna confirms that those endowed with faith who fix their consciousness on Him continuously and worship Him exclusively, performing all activities invariably for Him are yuktatamah the most superior.
