It is recommended to study these courses first:

  1. Mantras for health & well-being
  2. Understanding well-being in the Veda
  3. Sūya - finding your inner light

The Sūktams & Gaṇapati Upaniṣat courses can be studied in any order. However, I recommend learning the Devī Sūktam & Puruṣa Sūktam after you have learnt at least 2 other Sūktams.
