Consider the following statements regarding the social impact of the Bhakti and Sufi movements in medieval India:
1. They successfully eradicated the varna and caste systems, leading to a completely egalitarian society by the 17th century.
2. They challenged the spiritual monopoly of the Brahmanas and the Ulema by asserting that salvation was accessible to all, irrespective of birth.
3. Paradoxically, some egalitarian sects born out of these movements eventually crystallized into new, rigid castes themselves over time.
Which of the statements given above are correct?
