Guru's eternal presence

Most of us trust the living masters less and about those who left their mortal bodies, we say that then was a better time. About those latter ones, we say that such masters don't exist any more. We even say that we should have been born around that time for our spiritual upliftment and such.

Its okay if one doesn't feel inclined towards gurus of this day, but if one does think that there have been great personalities in the past, there's no reason to be saddened that they aren't around any more in flesh and blood. In doing so, we would be undermining their teachings! Didn't they declare that the soul that they merged into is ananta... eternal? That after realization, there isn't a feeling of separation that they could relate to or even the so-called merging becomes a myth? That is inspiration enough to search for one's own guru, whether from the present or past (or even future!)

There are all ranges of radio waves present all around and depending on where one is placed, one needs to tune the receiver to the correct frequency using the right antenna. Similarly, depending on what our inclinations are (made from karmic past, of course), we need to tune into our guru with the right faith. The guru is omnipresent, sarvadhi saakshi, transcending all that we think are obstacles to us. Then why limit our thinking to what era we live in and give up? Instead, shouldn't we be looking within and/or without on the right wavelength of spirituality?
