The Death's Head is the symbol of the Asura (the adversary of the gods) vanquished and killed by the Divine Power.
You have only to set about resolutely slaying the Rakshasas and the doors will open to you as they have done to many others who were held up by their own mind or vital nature.
Normal human defects are one thing — they are the working of the lower nature of the Ignorance. The action of the hostile forces is a special intervention creating violent inner conflicts, abnormal depressions, thoughts and impulses of a kind which can be easily recognised as suggestions e.g. abandoning the yoga, revolt against the Divine, suggestions of calamity and catastrophe apparently irresistible, irrational impulses and so on. It is a different order from the usual human weakness.
Hostiles forces attack every sadhak; some are conscious of it, others are not. Their object is either to influence the person or to use him or to spoil his sadhana or the work or any other motive of the kind. Their object is not to test, but their attack may be used by the guiding power as a test.
If the faith and surrender are complete in all parts of the being then there can be no attack. If there is a strong central faith and surrender at all times, there can be attacks but the attacks will have no chance of success.
A sovereignty of tireless sweetness lived
Like as song of pleasure on the lips of Time.
A large spontaneous order freed the will,
A sun-frank winging of the soul to bliss,
The breadth and greatness of the unfettered act
And the swift fire-heart's golden liberty.
There was no falsehood of soul-severance,
There came no crookedness of thought or word
To rob creation of its native truth;
All was sincerity and natural force.
