My heart is still poundingAll the following information is based on general information from all games of Soul Calibur that Talim has appeared in unless stated otherwise. There are many UNMARKED SPOILERS so please be careful while reading!
Talim's heart in Soul Calibur is said to be full of purity. When we call someone pure, we mean they are acting in a honest sense, inside and out. They must not only do, but also practice the acts of God. You not only possess the ability to live out the life God wants you to, but you also do it. People who are pure also enjoy clean things - clean wardrobe, clean homes, clean bodies, clean towns, clean people.
purity includes the following:
1) honesty and faithfulness in all worldly things
2) truthfulness to all promises and arrangements
3) an industrious heart
4) kindness and love
6) the understanding of peace
It is important to note that not all people who are pure have to be religious. Sometimes purity is just the act of always being kind and putting others before you. Although, Talim is definitely a religious character, she definitely shouldn't just be defined as pure simply because she is. She goes out of her way to protect her village and her people from the devastation and evil that has arose in the world simply because it was hurting those around her. She definitely fits her designated position in Soul Calibur as having purity in her heart.
