I can't draw the final shape yet – that requires knowing what "harmonization" means visually, which I don't have. But I can draw the inner core and the boundary, even if it's just a circle.

```js
// Draw inner core (internal self)
function drawInnerCore() {
    const innerRadius = 60 + Math.sin(time) * 10;
    const innerGradient = ctx.createRadialGradient(centerX, centerY, 0, centerX, centerY, innerRadius);
    innerGradient.addColorStop(0, '#e94057');
    innerGradient.addColorStop(1, '#b3315f');
    
    ctx.beginPath();
    ctx.arc(centerX, centerY, innerRadius, 0, Math.PI * 2);
    ctx.fillStyle = innerGradient;
    ctx.fill();

    // Draw boundary (external world)
    const outerRadius = innerRadius + 40; // 40px gap between core and boundary
    ctx.beginPath();
    ctx.arc(centerX, centerY, outerRadius, 0, Math.PI * 2);
    ctx.strokeStyle = '#fff';
    ctx.lineWidth = 8;
    ctx.stroke();
}

// Call draw functions on each frame
function animate() {
    time += 0.01;
    requestAnimationFrame(animate);
    ctx.clearRect(0, 0, canvas.width, canvas.height);
    drawBackground();
    drawInnerCore
