1) The 6 kinds of daily activity a devotee MUST perform
Srimad-Bhagavatam 7.9, Summary
Although being silent, observing austerities and penances, learning the Vedic literature, undergoing ritualistic ceremonies, living in a solitary place and performing japa and transcendental meditation are approved means of liberation, they are meant for nondevotees or for cheaters who want to live at the expense of others. A pure devotee, however, being freed from all such deceptive activities, is able to see the Lord face to face.
…One should therefore always engage in devotional service by offering respectful obeisances to the Lord, offering prayers, working for the Lord, worshiping the Lord in the temple, always remembering the Lord and always hearing about His transcendental activities.
Without these six kinds of activity, one cannot attain to devotional service.
2) Qualifications for going back to Godhead
Bhagavad-gita 18.55
One can understand the Supreme Personality as He is only by devotional service. And when one is in full consciousness of the Supreme Lord by such devotion, he can enter into the kingdom of God.
3) What should our daily activity become?
Srimad-Bhagavatam 7.6.24, Purport
…. As one performs this service for humanity, without discrimination between friends and enemies, the Lord becomes satisfied, and the mission of one's life is fulfilled.
Sri Chaitanya Mahaprabhu therefore advised everyone to become a guru-devotee and preach Krishna consciousness (yare dekha, tare kaha 'krsna'-upadesa). That is the easiest way to realize the Supreme Personality of Godhead. By such preaching, the preacher becomes satisfied, and those to whom he preaches are also satisfied. This is the process of bringing peace and tranquillity to the entire world.
(And of course we know this means to become siksa guru, not diksa guru)
4) And how do we do all the above? What is the actual process?
Bhagavad-gita 4.10, Transcendental Knowledge, Purport
adau sraddha tatah sadhu-
sango 'tha bhajana-kriya
tato 'nartha-nivrttih syat
tato nistha rucis tatah
athasaktis tato bhavas
tatah premabhyudancati
sadhakanam ayam premnah
pradurbhave bhavet kramah
"In the beginning one must have a preliminary desire for self-realization. This will bring one to the stage of trying to associate with persons who are spiritually elevated. In the next stage one becomes initiated by an elevated spiritual master, and under his instruction the neophyte devotee begins the process of devotional service. By execution of devotional service under the guidance of the spiritual master, one becomes free from all material attachment, attains steadiness in self-realization, and acquires a taste for hearing about the Absolute Personality of Godhead, Sri Krishna. This taste leads one further forward to attachment for Krishna consciousness, which is matured in bhava, or the preliminary stage of transcendental love of God. Real love for God is called prema, the highest perfectional stage of life." In the prema stage there is constant engagement in the transcendental loving service of the Lord. So, by the slow process of devotional service, under the guidance of the bona fide spiritual master, one can attain the highest stage, being freed from all material attachment, from the fearfulness of one's individual spiritual personality, and from the frustrations resulting from void philosophy. Then one can ultimately attain to the abode of the Supreme Lord.
5) What kind of Maya can stop us from succeeding in our spiritual life?
Srimad-Bhagavatam 7.7.1, What Prahlada Learned in the Womb, Purport
When he was in the womb of his mother, Prahlada Maharaja listened to the words of Narada Muni. One cannot imagine how the baby in embryo could hear Narada, but this is spiritual life; progress in spiritual life cannot be obstructed by any material condition. This is called ahaituky apratihata. Reception of spiritual knowledge is never checked by any material condition.
