SB Canto 3

Your visit to Me in this lonely place because of your pure and unflinching devotional service is a great boon for you.

SB 3.4.12, Translation: O honest one, your present life is the last and the supermost because in this term of life you have been awarded My ultimate favor. Now you can go to My transcendental abode, Vaikuṇṭha, by leaving this universe of conditioned living entities. Your visit to Me in this lonely place because of your pure and unflinching devotional service is a great boon for you.

This transcendental, eternal form of Your personality can be understood only by Your mercy, through unflinching devotional service, by great sages whose hearts have been purified in the devotional way.

SB 3.15.47, Translation: We know that You are the Supreme Absolute Truth, the Personality of Godhead, who manifests His transcendental form in the uncontaminated mode of pure goodness. This transcendental, eternal form of Your personality can be understood only by Your mercy, through unflinching devotional service, by great sages whose hearts have been purified in the devotional way.

A sādhu is described in Bhagavad-gītā as one who unflinchingly engages in devotional service.

SB 3.25.20, Purport: Here it is recommended that attachment should be transferred to the self-realized devotees, the sādhus. And who is a sādhu? A sādhu is not just an ordinary man with a saffron robe or long beard. A sādhu is described in Bhagavad-gītā as one who unflinchingly engages in devotional service. Even though one is found not to be following the strict rules and regulations of devotional service, if one simply has unflinching faith in Kṛṣṇa, the Supreme Person, he is understood to be a sādhu. Sādhur eva sa mantavyaḥ [Bg. 9.30]. A sādhu is a strict follower of devotional service. It is recommended here that if one at all wants to realize Brahman, or spiritual perfection, his attachment should be transferred to the sādhu, or devotee. Lord Caitanya also confirmed this. Lava-mātra sādhu-saṅge sarva-siddhi haya: [Cc. Madhya 22.54] simply by a moment's association with a sādhu, one can attain perfection.
