favorably;  sarva-indriye —with all the senses;  krṣṇa-anuśilana —cultivation of Krṣṇa consciousness
TRANSLATION
“A pure devotee must not cherish any other desire than to serve Krṣṇa. He should not offer worship to the demigods or to mundane personalities. He should not cultivate artificial knowledge, which is devoid of Krṣṇa consciousness, and he should not engage himself in anything other than Krṣṇa conscious activities. One must engage all one’s purified senses in the service of the Lord. This is the favorable execution of Krsna conscious activities.

TRANSLATION
“These activities are called śuddha-bhakti, pure devotional service. If one renders such pure devotional service, he develops his original love for Kṛṣṇa in due course of time. In Vedic literatures like the Pañcarātras and Śrīmad-Bhāgavatam, these symptoms are described.
PURPORT
One has to develop his devotional service under the directions of a pure devotee, the spiritual master, and in accordance with the Vedic directions given in the  Pañcarātra  and  Bhāgavatam  systems. The  Pañcarātra  system includes methods of temple worship, and the  Bhāgavatam  system includes the spreading of Kṛṣṇa conscious philosophy through the recitation of  Śrimad-Bhāgavatam  and the discussion of philosophy with people who are interested. Through discussion, one can create an interest and understanding of the  Pañcarātra  and  Bhāgavatam  systems.
