Re: Worship to Lord Brahma
In Shiva Purana we have a story where both Vishnu and Brahma try to locate the beginning and end of Lord Shiva. Vishnu accepts his inability to do so, and Lord Shiva is pleased and confers on him the ability to do so. But Brahma lies that he was able to do so - and is cursed by Shiva to be avoided by people. That is why Brahma is not worshipped.
But it is a fact that Brahma worship was there even till the 5th century A.D because varahamihira explains the construction of the murtis of brahma. There is still a temple for brahma at pushkar in Rajasthan.
There is no reason why some one should not worship Brahma, and I am assuming that it still exists in the form of Sarasvati. ( we still celebrate Sarasvati puja during navaratri festivals)
He is the one on whom our hope depends. For if Hanuman survives, all we though dead are yet alive. But if his precious life be lost though living still we are but dead: He is our hope and sure relief -Jambavan (Yuddha Kanda. 74). Impossibility=Hanuman
