Seeking Guidance on the Path to Islam

As-salamu alaykum. I'm coming from a Hindu background and have recently felt drawn to exploring Islam as my faith. I've been feeling a bit distant from my current understanding of religion and am sincerely looking into Islam for spiritual direction. Right now, I'm in a phase of reflection and have many questions. I was hoping for some supportive advice. Specifically, I'd appreciate knowing: 1. What was the moment or understanding that made you certain about Islam? How did you come to know it is the truth? 2. Could you recommend helpful resources like books or online content for someone who is still contemplating? (I've found some beneficial channels). 3. Regarding cultural celebrations like Diwali or Holi, would I need to stop observing them completely, or is social participation with family acceptable? 4. What about traditional clothing such as Saris or cultural signs of respect like touching elders' feet? 5. Is the Hijab obligatory? I'm striving to understand the wisdom behind it. I am seeking clarity and would be grateful for any kind guidance. Jazakum Allahu khayran.
