I keep things equal, left and right, I'm what you need when walking a tight height. Lose me and you'll stumble or fall, find me and you'll stand up tall. What am I?

I once was tall in forest deep, Where birds would sing and squirrels leap. Now polished smooth beneath your feet, I make your home look warm and neat.

In a twist, I bring forth day from night, a glass blossom that banishes fright. Filament's whisper, a spark's delight, casting shadows to dance in my soft, warm light.

Tall seat, no backrest, For a drink, I offer perch, Balance, my true test.

A pillar of wax, Providing warmth to families worldwide, I often come in an array of lovely scents
