user11541: Buddha said he taught only the suffering , origin of suffering , cessation of suffering and path to cessation of suffering. 
He also said whatever arises must perish and that is why whatever arises is a source of suffering. 
However Buddha arises too. 
Therefore is it correct to say that Buddha is also a source of suffering?

user254: I think that the Agama you quoted -- here -- is intended to teach that the Dharma (or Dhamma) is unconditioned.

Whether a Tathāgata arises in the world or not, this element of dharma remains unchanging.

In other suttas the Dharma is also described as "timeless" (or perhaps "ever-present" or "continuous" depending on how akalika is translated).
Note too that "the Dhamma" is described as "a dhamma" -- it's not a "sankhara", (i.e. not a compound thing or composite thing). The Dhamma says that it's sankharas (not dhammas) that are impermanent. Nibbana is an example of a not-impermanent dhamma.
Back to the Buddha:

When asked whether the Tathagata exists or doesn't exist after death, I think that the canonical answer was:

It's inappropriate to associate the Tathagata with the aggregates
You're therefore unable to identify the Tathagata even when he's alive

In the time leading up to the Buddha's parinibbana, some of his attendants (e.g. Ananda) seemed reluctant to accept that.

Then the Venerable Ananda went into the vihara and leaned against the doorpost and wept:

"I am still but a learner, and still have to strive for my own perfection. But, alas, my Master, who was so compassionate towards me, is about to pass away!"


Maybe that (i.e. their attachment) was a source of suffering.
In various suttas, we're told to associate the Buddha with the Dharma -- for example, SN 22.87:

For a long time, Lord, I have wanted to come and set eyes on the Blessed One, but I had not the strength in this body to come and see the Blessed One."
Enough, Vakkali! What is there to see in this vile body? He who sees Dhamma, Vakkali, sees me; he who sees me sees Dhamma. Truly seeing Dhamma, one sees me; seeing me one sees Dhamma.

This doctrine is developed or repeated in later forms of Buddhism (see dharmakāya).

So to the extent that the Buddha is the Dharma, and to the extent that the Dharma is unconditioned and timeless, I wouldn't view the Tathagata as conditioned.
I think I also associate with the Tathagata with Nibanna -- as an answer to any question like, "where is the Tathagata?" and "what does he experience?" -- and that (Nibbbana) isn't "suffering" either.

If I want to posses or be Buddha then I will suffer.
Maybe so.
I guess that Siddhartha Gautama discovered or realised something similar, during his search for enlightenment -- something like, "When I want to become enlightened, I suffer. To be enlightened, you have to stop wanting (craving and attachment)."
I think that's explicit in some suttas like the Brahamana Sutta (in that sutta, "going to the park" might also be a metaphor for becoming a monk ... because in those days, monasteries were just parks -- "forest monasteries").
And I think there are doctrines and practices in Mahayana to try to get over that (perhaps, I'm not sure, the "original nature" or "Buddha nature" doctrine; not to mention "tantrayana").
Maybe you're projecting something (is "projection" a concept in Buddhism?)? -- see this answer where someone starts by wanting to see himself as a good monk, the best monk ... later, perhaps more maturely, as "just a monk". Should even the Buddha, as a person, be seen as "a monk"?
But anyway if you think that "wanting to be Buddha" and so on is problematic you might find it less uncomfortable to identify as "a Buddhist" rather than "a Buddha" -- see for example this answer; or, this answer summarising different forms of buddhism.

user471: The Buddha is a source of suffering if you cling to his form, but not his teachings. By understanding the Buddha's teachings, you understand what is great and important about him. His form or voice or personality is not considered as great or important as his teachings.
Even his teachings (the Dhamma) are meant to be a raft that carries one to the other shore (Nibbana) but one should not cling to it, as one might cling to a raft after crossing the river.
From the Vakkali Sutta:

"For a long time, Lord, I have wanted to come and set eyes on the
  Blessed One, but I had not the strength in this body to come and see
  the Blessed One."
"Enough, Vakkali! What is there to see in this vile body? He who sees
  Dhamma, Vakkali, sees me; he who sees me sees Dhamma. Truly seeing
  Dhamma, one sees me; seeing me one sees Dhamma."
