A flower never asks how and why it blossomed.
It just lets itself bloom.
Surrender.
Let go.
And all the asanas, mudras, bandhas... every spirtiual secret will be revealed to you itself.
Because they are your birthright.
You contain everything within you. Just like a seed contains the tree in it.
The smile on your face represents a certain state within you. Similarly all the asanas, mudras, bandhas represent a certain state within.
Just surrender to the one dwelling within your heart.
Trust!
Pray!
And it will reveal your most secret beauty to you.
Because it loves you.
