Planet Earth is where we belong to. The Earth is our place our home hence वसुधैव कुटुम्बकम्. Whoever we are, our ultimate goal is living healthy life, helping each other, evolve our wisdom. In order to achieve these we either choose or destined to practice different religions. However our ultimate goal remains unchanged. Where ever we come from when it comes to wisdom we know the ancient knowledge from the Indian subcontinent is a real gem.

That is evident in rich cultures of different geographical regions within the subcontinent, or in the very coherent bond of Indian families, or even in it's unbreakable spirit; this all speak of the honed wisdom. 

Across the world many universities have harnessed the sacred knowledge and implemented them in economics, leadership, evaluation, entity structures, humanity etc. Not just that but also many philosophies and religions have been derived from it which are inspiring and enlightening many many people in our home. This ultimate wisdom is सनातन.

The question though we always wonder with that where to get authentic content. That is why I'm listing some authentic sources to learn.

However my advice is 

1. Try to find a right mentor.

2. Encompass the unbiases, foster the people and nature around.

3. To infer the pure meaning of texts, keep getting yourself proficient in respective ancient language संस्कृत.
