As the chariot of air carries an aroma from its source and immediately catches the sense of smell, similarly, one who constantly engages in devotional service, in Kṛṣṇa consciousness, can catch the Supreme Soul, who is equally present everywhere. (S.B.3:29:20).

vinirdhutāśeṣa-mano-malaḥ pumān
asańga-vijñāna-viśeṣa-vīryavān
yad-ańghri-mūle kṛta-ketanaḥ punar
na saḿsṛtiḿ kleśa-vahāḿ prapadyate

When a devotee takes shelter at the lotus feet of the Supreme Personality of Godhead, he is completely cleansed of all misunderstanding or mental speculation, and he manifests renunciation. This is possible only when one is strengthened by practicing bhakti-yoga. Once having taken shelter at the root of the lotus feet of the Lord, a devotee never comes back to this material existence, which is full of the threefold miseries.
(S.B.4:21:32).

sā śraddhayā bhagavad-dharma-caryayā
jijñāsayādhyātmika-yoga-niṣṭhayā
yogeśvaropāsanayā ca nityaḿ
puṇya-śravaḥ-kathayā puṇyayā ca

Attachment for the Supreme can be increased by practicing devotional service, inquiring about the Supreme Personality of Godhead, applying bhakti-yoga in life, worshiping the Yogeśvara, the Supreme Personality of Godhead, and by hearing and chanting about the glories of the Supreme Personality of Godhead. These actions are pious in themselves. (S.B.4:22:22).

athātmano 'rtha-bhūtasya
yato 'nartha-paramparā
saḿsṛtis tad-vyavacchedo
bhaktyā paramayā gurau

The real interest of the living entity is to get out of the nescience that causes him to endure repeated birth and death. The only remedy is to surrender unto the Supreme Personality of Godhead through His representative. Unless one renders devotional service unto the Supreme Personality of Godhead, Vāsudeva, one cannot possibly become completely detached from this material world, nor can he possibly manifest real knowledge.
(S.B.4:29:36-37).

sa vai priyatamaś cātmā
yato na bhayam aṇv api
iti veda sa vai vidvān
yo vidvān sa gurur hariḥ

One who is engaged in devotional service has not the least fear in material existence. This is because the Supreme Personality of Godhead is the Supersoul and friend of everyone. One who knows this secret is actually educated, and one thus educated can become the spiritual master of the world. One who is an actually bona fide spiritual master, representative of Kṛṣṇa, is not different from Kṛṣṇa. (S.B.4:29:51).

gṛheṣv āviśatāḿ cāpi
puḿsāḿ kuśala-karmaṇām
mad-vārtā-yāta-yāmānāḿ
na bandhāya gṛhā matāḥ

Those who are engaged in auspicious activities in devotional service certainly understand that the ultimate enjoyer or beneficiary of all activities is the Supreme Personality of Godhead. Thus when one acts, he offers the results to the Supreme Personality of Godhead and passes life always engaged in the topics of the Lord. Even though such a person may be participating in family life, he is not affected by the results of his actions.
(S.B.4:30:19).

śrutena tapasā vā kiḿ
vacobhiś citta-vṛttibhiḥ
buddhyā vā kiḿ nipuṇayā
balenendriya-rādhasā

Without devotional service, what is the meaning of severe austerities, the process of hearing, the power of speech, the power of mental speculation, elevated intelligence, strength, and the power of the senses? (S.B.4:31:11).

yathā taror mūla-niṣecanena
tṛpyanti tat-skandha-bhujopaśākhāḥ
prāṇopahārāc ca yathendriyāṇāḿ
tathaiva sarvārhaṇam acyutejyā

As pouring water on the root of a tree energizes the trunk, branches, twigs and everything else, and as supplying food to the stomach enlivens the senses and limbs of the body, simply worshiping the Supreme Personality of Godhead through devotional service automatically satisfies the demigods, who are parts of that Supreme Personality. (S.B.4:31:14).

na bhajati kumanīṣiṇāḿ sa ijyāḿ
harir adhanātma-dhana-priyo rasa-jñaḥ
śruta-dhana-kula-karmaṇāḿ madair ye
vidadhati pāpam akiñcaneṣu satsu

The Supreme Personality of Godhead becomes very dear to those devotees who have no material possessions but are fully happy in possessing the devotional service of the Lord. Indeed, the Lord relishes the devotional activities of such devotees. Those who are puffed up with material education, wealth, aristocracy and fruitive activity are very proud of possessing material things, and they often deride the devotees. Even if such people offer the Lord worship, the Lord never accepts them. (S.B.4:31:21).

tasmān naro 'sańga-susańga-jāta-
jñānāsinehaiva vivṛkṇa-mohaḥ
hariḿ tad-īhā-kathana-śrutābhyāḿ
labdha-smṛtir yāty atipāram adhvanaḥ

Simply by associating with exalted devotees, anyone can attain perfection of knowledge and with the sword of knowledge can cut to pieces the illusory associations within this material world. Through the association of devotees, one can engage in the service of the Lord by hearing and chanting (śravaṇaḿ kīrtanam). Thus one can revive his dormant Kṛṣṇa consciousness and, sticking to the cultivation of Kṛṣṇa consciousness, return home, back to Godhead, even in this life. (S.B.5:12:16).
