Since the Spirit Container had been fused with a mineral, it was pretty stable. That allowed Inala to use his Skill of Palm Stitch to pretty much stitch the Spirit Container onto his palm, using the tension to knead the Spirit Container like a dough and make it expand along the print on his palm.
Currently, it had overlaid perfectly, becoming one with the palm print. As long as Inala remains careful with his palms and doesn't slap them on rocks nonstop, the palm print won't be damaged.
It meant he could use the Vara Palm Stitch as if it were a Vara Human Avatar. That was possible. And if he so needed, he could instantly use Palm Stitch to stitch the Vara Palm Print onto any surface and make it emanate its respective power there.
