You have to first decide your relationship to God.
But in order to realize God, one must assume one of these attitudes:
santa, dasya, sakhya, vatsalya, or madhur.
"Santa, the serene attitude. The rishis of olden times had this
attitude toward God. They did not desire any worldly enjoyment. It is
like the single-minded devotion of a wife to her husband. She knows
that her husband is the embodiment of beauty and love, a veritable
Madan.
"Dasya, the attitude of a servant toward his master. Hanuman had this
attitude toward Rama. He felt the strength of a lion when he worked
for Rama. A wife feels this mood also. She serves her husband with all
her heart and soul. A mother also has a little of this attitude, as
Yasoda had toward Krishna.
"Sakhya, the attitude of friendship. Friends say to one another, 'Come
here and sit near me.' Sridama and other friends sometimes fed Krishna
with fruit, part of which they had already eaten, and sometimes
climbed on His shoulders.
"Vatsalya, the attitude of a mother toward her child. This was
Yasoda's attitude toward Krishna. The wife, too, has a little of this.
She feeds her husband with her very life-blood, as it were. The mother
feels happy only when the child has eaten to his heart's content.
Yasoda would roam about with butter in her hand, in order to feed
Krishna.
"Madhur, the attitude of a woman toward her paramour. Radha had this
attitude toward Krishna. The wife also feels it for her husband. This
attitude includes all the other four."

Prahlada’s nine points of devotion
Hearing about Vishnu, singing about Him, remembering Him, serving Him,
saluting Him, being His servant, being His comrade, and surrendering
oneself and everything that is one’s own to Him – these are the nine
aspects of Bhakti or God-love. If man could be trained to practice
devotion characterized by these nine features that indeed would be the
highest education he could have.
Srimad Bhagavata Purana VII.5.23-24
Service to humanity
I abide in all beings as their inner-most soul. Disregarding My
presence within them, men make a show of worshiping Me through images.
If one disregards Me present in all as their soul and Lord but
ignorantly offers worship only to images, such worship is as
ineffective as a sacrificial offering made in ashes. A man who
persecutes Me residing in others, who is proud and haughty, who looks
upon God as the other – such a person will never attain to peace of
mind. If a man disregards and persecutes fellow beings, but worships
Me in images with numerous rituals and rich offerings, I am not at all
pleased with him for proffering such worship. A man should, however,
worship Me in images, side by side with discharging his duties, which
include the love of all beings, until he actually realises My presence
in in himself and in all beings. As long as man is self-centred and
makes an absolute distinction between himself and others (without
recognising the unity of all in Me, the Inner Pervader), he will be
subject to the great fear of Death (including every form of
deprivation of self-interest). So, overcoming the separateness of a
self-centred life, one should serve all beings with gifts, honour and
love, recognising that such service is really being rendered to Me who
reside in all beings as their innermost soul.
