The journey of spiritual growth in Hinduism is largely focused on realising the Atman's true nature, transcending the illusion of separateness (Maya) and achieving unity with the Brahman. This realisation, known as self-realisation or Atman-Brahman unity, is the pinnacle of spiritual achievement, leading to liberation (Moksha) from the cycle of birth, death, and rebirth (Samsara), and the attainment of eternal bliss.'
