To be sure to put the Lord in our mind as He recommends Himself to us and to constantly think of Him, the ideal is to chant the Holy Names of Krishna in the morning, right after brushing yourself teeth and took a shower, then throughout the day, and finally in the evening just before going to bed.
The Lord said: Whoever, at the death, at the very moment of leaving the body, remembers Me alone, immediately reach My abode, do not doubt it.
Logos 423
To be free from fear in the face of death, we must listen to, glorify and remember Krishna, God, the Supreme Person.
The Lord is the Supreme Soul also called the Holy Spirit, located in each being, as well as the Supreme Master located in the heart of each living being. So whether we become attached to God in one way or another, and the Lord will take care to protect us from all peril.
Whoever becomes a devotee of the Lord will never perish, unlike any other, for perishing means remaining chained to the cycle of repeated deaths and rebirths, thus letting escape the unparalleled grace of having attained human form. Ignoring the fate reserved for him by the laws of material nature, the being who does not use his human form in order to develop his consciousness of God and thus achieve spiritual realization, will be plunged into the whirlwind of the dead and the successive rebirths. He will thus have to take up a material body in one or other of the 8,400,000 species of living beings, always further from his spiritual condition.
In the diversity of living species, the incarnate being does not know under which form, animal or plant, it will have to be reborn. This is why it is absolutely necessary to revive our original consciousness, the consciousness of Krishna, also called consciousness of God.
We must remember the glories and other entertainments of God, sing the hymns of His Holy Names, and of one way or another we can apply ourselves to directing our thoughts towards the Lord and thus succeed in putting him in our mind with the greatest seriousness. This is how one becomes free from all fear of death.
The incarnate being does not know anything about his destiny after death, because of the total domination exercised over him by the laws of material nature. Now Krishna, God, the Supreme Person, is the sole Master of natural laws, so that in taking serious refuge in Him, we will see all fear of falling again in the midst of so many species disappear.
The sincere holy being is assured of reaching the abode of the Lord in his absolute and eternal kingdom.
