Desiring liberation, that is called mukti, and . . . Or become one with the Supreme Brahman, that is mukti. And siddhi, yogīs, they are trying to achieve some success in aṣṭa-siddhi, aṇimā, laghimā. So everyone is desiring. So therefore Kṛṣṇa Caitanya Mahāprabhu says, kṛṣṇa-bhakta niṣkāma: "A devotee of Kṛṣṇa is not desirous of anything, either bhukti, mukti or siddhi." The purport is, so long you desire something, you'll never get peace of mind. And a bhakta does not desire anything. He is satisfied in any position, whatever is offered to him by Kṛṣṇa.
- nārāyaṇa-parāḥ sarve
- na kutaścana bibhyati
- svargāpavarga-narakeṣv
- api tulyārtha-darśinaḥ
- (SB 6.17.28)
Anyone who is nārāyaṇa-parāyaṇa, he does not fear whether he is going to hell or heaven, because wherever he goes he is with Nārāyaṇa, he is safe. It doesn't matter whether it is hell or heaven.
That is offered by Śrī Caitanya Mahāprabhu in His prayer,
- na dhanaṁ na janaṁ na sundarīṁ
- kavitāṁ vā jagadīśa kāmaye
- mama janmani janmanīśvare
- bhavatād bhaktir ahaitukī . . .
- (CC Antya 20.29, Śikṣāṣṭaka 4)
The idea is that a bhakta does not require any material happiness or distress. He does not require any monistic proposition to merge into the existence of the Supreme. And neither he desires any jugglery of aṣṭa-siddhi yogam.
