About the course
Inner Transformation: An Introduction to Interspirituality is a self-paced online course from ProSocial World that invites you to explore your inner life and consider how it connects to the world around you.
The course starts from a simple but profound idea: that our spiritual evolution, individually and collectively, matters more than we might realise. The way we move through the world — how we treat each other, how we care for other living beings, how we respond to injustice — is shaped by something deeper than habit or intention. This course is an invitation to tend to that deeper place.
Over about 90 minutes, the course moves through three themes, each explored through short videos, poems, reflection, and simple practices for carrying the ideas into daily life:
- Interconnectedness: what it means to recognise our fundamental belonging to each other and to the world
- Inner Transformation: the practices and orientations that support genuine inner growth
- Social Engagement: how a deepened inner life calls us outward, toward justice, care, and service
The course draws on Dr. Wayne Teasdale's Nine Elements of Universal Spirituality, developed over decades of interspiritual practice and dialogue, and on the broader idea that the world's traditions —for all their differences— share something essential about what it means to grow as a human being.
