Why is it that gods do this? Adi Shankaracharya says there are 3 people stopping one from self-realization:
- The individual himself
- Other people
- Devas
Swami Sarvananda in his commentary on the Taittiriya Upanishad says,
This invocation is chanted because it is believed that even gods thwart the path of an aspirant striving for God-realization. So, if they are propitiated in the beginning, the course is expected to go smoother.
The invocation he is speaking of is: "Sam no Mitrasam Varunaha.... etc"
But why would Devas do this? Isn't it an Asuric or Raksha quality to stop people from worshipping? Throughout Smrti Asuras and Rakshasas disrupt Yajnas, etc.
However, in the Vedas we see Devas themselves teaching others how to realize God. Devas are probably self realized if they teach others about it. In the Kaushitaki Upanishad there is the conversation between Indra and Pratardana. Pratardana asks Indra to give him a boon that he wants, and Indra says to meditate on Brahman.
In the Bhrigu Valli of the Taittiriya Upanishad, Varuna, who is the father of Bhrigu, teaches Bhrigu about Brahman and how to meditate on him.
Now in the Itihasas Indra tries to stop people from gaining tapo-shakti, but this is different from attaining Brahma-Vidya.
So why would Devas stop people?
