Dear friend
Your words are of a deep truth. But i have never talked about adopting the vows of sanyasa right now but about being initiated and living in an ashram for some years.
Yes, probably i aim too high, but this is a must if we don't want to overide opportunities that may come across us. First we aim to the highest (highest in the sense of accordance to our preferences, never think that i mean a tantric guru is higher than others), and little by little as life fixes us we keep adjusting until we match what we really deserve or are destined to bear. A yoga vedanta guru would be perfect, a hatha yoga one too... and so forth.
Concerning to Karma Yoga, yes, i have to practice more, my heart still has some thorns to pluck.
Anyway, the stay in India will worth, i'm totally sure.
Gods bless you
