Srimad-Bhagavatam: Canto 8 - Chapter 1 - Verse 23
यत्पादयोरशठधी: सलिलं प्रदायदूर्वाङ्कुरैरपि विधाय सतीं सपर्याम् ।अप्युत्तमां गतिमसौ भजते त्रिलोकींदाश्वानविक्लवमना: कथमार्तिमृच्छेत् ॥ २३ ॥
yat-pādayor aśaṭha-dhīḥ salilaṁ pradāyadūrvāṅkurair api vidhāya satīṁ saparyāmapy uttamāṁ gatim asau bhajate tri-lokīṁdāśvān aviklava-manāḥ katham ārtim ṛcchet
By offering even water, newly grown grass, or flower buds at Your lotus feet, those who maintain no mental duplicity can achieve the most exalted position within the spiritual world. This Bali Mahārāja, without duplicity, has now offered everything in the three worlds. How then can he deserve to suffer from arrest?
In Bhagavad-gītā (9.26) it is stated: The Supreme Personality of Godhead is so kind that if an unsophisticated person, with devotion and without duplicity, offers at the lotus feet of the Lord a little water, a flower, a fruit or a leaf, the Lord accepts it. Then the devotee is promoted to Vaikuṇṭha, the spiritual world. Brahmā drew the Lord’s attention to this subject and requested that He release Bali Mahārāja, who was suffering, being bound by the ropes of Varuṇa, and who had already given everything, including the three worlds and whatever he possessed.
