In the beginning of the discharge of devotional service there are some regulative principles, if a devotee observes principles, surely he will quickly make good advancement in Kṛṣṇa consciousness...
The first are the primary ten regulative principles. Then come the secondary ten regulative principles, and added to these are forty-four other activities. So all together there are sixty-four items for discharging the regulative practice of devotional service...
The primary ten regulative principles
(1) accepting the shelter of the lotus feet of a bona fide spiritual master,
(2) becoming initiated by the spiritual master and learning how to discharge devotional service from him,
(3) obeying the orders of the spiritual master with faith and devotion,
(4) following in the footsteps of great acaryas (teachers) under the direction ofthe spiritual master,
(5) inquiring from the spiritual master how to advance in Krsna consciousness,
(6) being prepared to give up anything material for the satisfaction of the Supreme Personality of Godhead, Sri Krsna (this means that when we are engaged in the devotional service of Krsna, we must be prepared to give up something which we may not like to give up, and also we have to accept something which we may not like to accept), (7) residing in a sacred place of pilgrimage like Dvaraka or Vrndavana,
(8) accepting only what is necessary, or dealing with the material world only as far as necessary,
(9) observing the fasting day on Ekadasi and
(10) worshiping sacred trees like the banyan tree.
the secondary ten regulative principles
(1) One should rigidly give up the company of nondevotees.
(2) One should not instruct a person who is not desirous of accepting devotional service.
(3) One should not be very enthusiastic about constructing costly temples or monasteries.
(5) One should not be neglectful in ordinary dealings.

other activities forty-four regulative principles
(1) One should decorate the body with tilaka, which is the sign of the Vaiṣṇavas. (The idea is that as soon as a person sees these marks on the body of the Vaiṣṇava, he will immediately remember Kṛṣṇa. Lord Caitanya said that a Vaiṣṇava is he who, when seen, reminds one of Kṛṣṇa. Therefore, it is essential that a Vaiṣṇava mark his body with tilaka to remind others of Kṛṣṇa.)
(3) One should accept flowers and garlands that have been offered to the Deity and the spiritual master and put them on one's body.
(4) One should learn to dance before the Deity.
(5) One should learn to bow down immediately upon seeing the Deity or the spiritual master.
(6) As soon as one visits a temple of Lord Kṛṣṇa, one must stand up.
(7) When the Deity is being borne for a stroll in the street, a devotee should immediately follow the procession. (In this connection it may be noted that in India, especially in Viṣṇu temples, the system is that apart from the big Deity who is permanently situated in the main area of the temple, there is a set of smaller Deities which are taken in procession in the evening. In some temples it is the custom to hold a big procession in the evening with a band playing and a nice big umbrella over the Deities, who sit on decorated thrones on the cart or palanquin, which is carried by devotees. The Deities come out onto the street and travel in the neighborhood while the people of the neighborhood come out to offer prasāda. The residents of the neighborhood all follow the procession, so it is a very nice scene. When the Deity is coming out, the servitors in the temple put forward the daily accounts before Them: so much was the collection, so much was the expenditure. The whole idea is that the Deity is considered to be the proprietor of the whole establishment, and all the priests and other people taking care of the temple are considered to be the servants of the Deity. This system is very, very old and is still followed. So, therefore, it is mentioned here that when the Deity is on stroll the people should follow behind.)
(8) A devotee must visit a Viṣṇu temple at least once or twice every day, morning and evening. (In Vṛndāvanathis system is followed very strictly. All the devotees in town go every morning and evening to visit different temples. Therefore during these times there are considerable crowds all over the city. There are about five thousand temples in Vṛndāvana city. Of course it is not possible to visit all the temples, but there are at least one dozen very big and important temples which were started by the Gosvāmīs and which should be visited.)
(9) One must circumambulate the temple building at least three times. (In every temple there is an arrangement to go around the temple at least three times. Some devotees go around more than three times — ten times, fifteen times — according to their vows. The Gosvāmīs used to circumambulate Govardhana Hill.) One should also circumambulate the whole Vṛndāvana area.
(11) One must render personal service to the Deities.
(12) One must sing. (13) One must perform sańkīrtana.
(14) One must chant.
(15) One must offer prayers.
(16) One must recite notable prayers.
(18) One must drink caraṇāmṛta (water from the bathing of the Deities, which is offered to guests).
(19) One must smell the incense and flowers offered to the Deity.
(20) One must touch the lotus feet of the Deity.
(21) One must see the Deity with great devotion.
(25) One should remember the Deity.
(26) One should meditate upon the Deity.
(27) One should render some voluntary service.
(28) One should think of the Lord as one's friend.
(29) One should offer everything to the Lord.
(30) One should offer a favorite article (such as food or a garment).
(31) One should take all kinds of risks and perform all endeavors for Kṛṣṇa's benefit.
(32) In every condition, one should be a surrendered soul.
(33) One should pour water on the tulasītree.
(36) One should offer service to Vaiṣṇavas (devotees).
(37) One should arrange one's devotional service according to one's means.
(38) In the month of Kārttika (October and November), one should make arrangements for special services.
(40) One should do whatever is done with great care and devotion for the Deity.
(41) One should relish the pleasure of Bhāgavatam reading among devotees and not among outsiders.
(42) One should associate with devotees who are considered more advanced.
