In the 500 yoga teacher training, Yoga Skyros Greece, we looked into 43 asanas and continued our exploration of yoga history, anatomy, pranayama, mudras, dristhis, bandhas, chakras, meditation and the 5 bodies.
If you would like to look into the ancient books of yoga you may start with Patanjali, who is known as the father of yoga. It was written 2500 years ago, and is about achieving calmness with the present moment. It describes the eightfold path of Raja yoga towards enlightenment: Asanas, Pranayama, Niyama, Yama, Pratyahara, Dharana, Dhyana and Samadhi.
The Bhagavad Gita was written 5000 years ago and is a holy book. It is the story of Prince Arjuna going to war against his relatives. At the battlefield he is assisted by Krishna to find the way out of this situation. Arjuna experiences a battlefield inside and outside, Krishna encourages him to find his true nature and be conciousness of the true self.
There are two purification books, the Gheranda Samhita and the Hatha Yoga Pradipika, they were written about 3000 years ago.
Finally you may look into the Upanishades, collection of sutras, they are an explanation of the Vedas, and are dealing with the esoteric aspects of yoga, like the chakras and nadis.
