By my own measure of good and Light. It would be my perception, of course. If she shows me a way to walk towards Light and away from darkness; if she encourages my strengths as opposed to my weaknesses; if she asks me, and shows by example, never to do anything that makes me weak. If she directs me to the Heart-room and not that of the mind.
She would demonstrate impartiality and by so doing correct me when I'm wrong or moving away from all that seems wholesome and grant or promote peacefulness. I would cherish a mother that teaches education and knowledge, ever reminding me that wisdom is in fact infinitely greater, and that experience is the greatest teacher, not books.
Still, I would love a holistic mum, one that recognises that the whole orange is important and each part has a role to play: the rind, peel or skin; the outer covering, flesh and seeds and even the juice! In the same way, I would hope that she teaches me to love scriptures, knowing that I can be inspired, but not so attached that I become blind.
I would look for her sacrifice, Love; fortitude and tenacity or steadfastness on the Path, and finally I would love to hear from her that there is light also in darkness and it can help me to grow.
