Sanatana

If I think there are only a few texts that are a foundational I think it will be the following:

• Hanuman Chalisa. Devotion and Service. What it means to be serve Isvara. I would further state that if there is only one text in Hindu dharma to study this would be it. Hanuman embodies what it means to be a devotee of Bhagavan. If we can embody him and live as selflessly as he did then we will have fulfilled dharma.
• Yoga Sutras of Patanjali. Practice of Yoga. The astanga system provides the framework for putting the other three texts into practice. Ironically, this text is the one most Westerners turn to but is relatively unknown within the Hindu community.
• Bhagavad Gita. Understand of Yoga. Understanding Karma, Bhakti, Raja and Jnana Yoga and messy reality of life. While this covers all the purusharta, I do think it speaks to artha in terms of Arjuna being a warrior and fulfilling his dharma even when life is messy.
• Vinjana Bhairava Tantra. Different forms of concentration.
