The four ancient yoga pathways to spiritual union taught in the Bhagavad Gita are built on the profound recognition, made by yoga masters thousands of years ago, that human beings have four faculties through which they can learn to purify the heart, discipline the mind, restrain the senses, and unite with the Self within: the intellect, love, psychic control, and work. Swami Vivekananda describes the four yogas as such:

“Each soul is potentially divine, and the goal of yoga is
 to manifest this Divinity within
 by controlling nature, external and internal.

"We can deny everything, except that we have the possibility of being better."

 ~ The Dalai Lama

We lament over our faults and shortcomings. We stress over all those things that don't turn out the way we would like. Yet, so long as we can remain open to the possibility that we can become better, we have the opportunity to grow and learn from our shortcomings and sufferings, becoming wiser, more joyful human beings as a result.

What you think of as your weaknesses are, most likely, blessings in disguise. Embrace your weaknesses. Be grateful for them. Turn them into your greatest strengths. Allow them to teach you - to transform yourself into a better being.
