This is not a very difficult process. However, one must learn it from an experienced person, from one who is already in the practice. The mind is always flying to this and that, but one must always practice concentrating the mind on the form of the Supreme Lord Śrī Kṛṣṇa or on the sound of His name. The mind is naturally restless, going hither and thither, but it can rest in the sound vibration of Kṛṣṇa. One must thus meditate on  paramaṁ puruṣaṁ , the Supreme Person, and thus attain Him. The ways and the means for ultimate realization, ultimate attainment, are stated in the  Bhagavad-gītā , and the doors of this knowledge are open for everyone. No one is barred out. All classes of men can approach the Lord by thinking of Him, for hearing and thinking of Him is possible for everyone.
The Lord further says::
māṁ hi pārtha vyapāśritya ye 'pi syuḥ pāpa-yonayaḥ striyo vaiśyās tathā śūdrās te 'pi yānti parāṁ gatim
kiṁ punar brāhmaṇāḥ puṇyā bhaktā rājarṣayas tathā anityam asukhaṁ lokam imaṁ prāpya bhajasva mām
“O son of Pṛthā, anyone who will take shelter in Me, whether a woman, or a merchant, or one born in a low family, can yet approach the supreme destination. How much greater then are the  brāhmaṇas , the righteous, the devotees, and saintly kings! In this miserable world, these are fixed in devotional service to the Lord.” (Bg. 9.32-33)
Human beings even in the lower statuses of life (a merchant, a woman or a laborer) can attain the Supreme. One does not need highly developed intelligence. The point is that anyone who accepts the principle of  bhakti-yoga  and accepts the Supreme Lord as the  summum bonum  of life, as the highest target, the ultimate goal, can approach the Lord in the spiritual sky. If one adopts the principles enunciated in  Bhagavad-gītā , he can make his life perfect and make a perfect solution to all the problems of life which arise out of the transient nature of material existence. This is the sum and substance of the entire  Bhagavad-gītā .
In conclusion,  Bhagavad-gītā  is a transcendental literature which one should read very carefully. It is capable of saving one from all fear.
nehābhikrama-nāśo ’sti pratyavāyo na vidyate svalpam apy asya dharmasya trāyate mahato bhayāt
“In this endeavor there is no loss or diminution, and a little advancement on this path can protect one from the most dangerous type of fear.” (Bg.
