Even if one given to extremely evil conduct, seeks Me (the Supreme) with unflinching devotion, he has to be regarded as noble; for, he is well resolved.
Krishna makes it clear that spirituality and devotion are open to all alike. Sinfulness is no bar to it. Somehow one must take to devotion and cultivate it exclusively. If and when one is able to feel exclusive devotion, then that supersedes all other considerations and demerits. Such a devotee is to be regarded as noble. Because he has taken the right resolve, which even the noble often fail to, with their professed merits.
To have exclusive devotion is rare indeed. The very object of being good and noble is actually to be fit for exclusive devotion. Out of great fortune and some deeper qualities, one becomes such a desirable devotee. And on this ground, he admittedly becomes noble.
Often the virtuous find it hard to make such a resolve, whereas this person, despite his unfavourable past, stands resolved and committed.
