Initially try to be regular, not daily
You want to establish a consistent habit. Don't sweat it if you miss a day. Do not make it a chore, or a task to mark off of your 'to do' list. Beginning, you want to get comfortable with sitting still and being silent. If you do that daily, then that's great. But, establishing a new personal constitution takes time. So just know...at first regularity is fine. A daily practice will develop out of regularity.
My second cautionary piece of advice for beginners is-
Do not get stuck on time
Many of us have heard the incredibly boastful reports from experienced practitioners and teachers of their countless hours spent in meditation. Someone that has vowed to begin jogging for the new year doesn't start by running marathons. A beginning meditation practice should not seek long sittings at first. Do not burden yourself with that unrealistic expectation. Five minutes can be a very good start. Set aside five minutes for a week to simply sit in silence. Go for ten minutes the next week and increase according to your comfort level after that. A spiritual practice is exactly the mirror image of a physical fitness program. One works the body into shape, the other works ones being into resilience.
Release all expectations before you start
Expectations can be the biggest contributor to disappointment. Expectation can blind you to the deep inner peace that a regular, effective esoteric practice offers. Expecting or looking for 'enlightenment' will distract you from the deeper knowing of yourself. You see, you already have a prejudice of what enlightenment looks like. You'll be looking for your preconceived idea, which is the perfect way to miss the deep knowing...the peaceful presence... the nuggets of wisdom that will bubble up from the core of your being. You want to go in naked of all presumption of what you're doing. Your sole intention is to seek the silence that is always with you. Let that show you what you need to be shown. You simply want to go in seeking silence and stillness, you want to develop the ability to see past your ego-mind.
Do not get into a struggle with your ego-mind
Your ego-mind never stops, not even when your sleeping. You do not silence your ego-mind when meditating. You develop the ability to see past it. You sink below, or above if you prefer; the distracting thoughts of the ego-mind. You're developing inner sight, the ability to rest in the still-silent presence that is always there. As Mooji says - "Let the noise be there" , Simply don't engage the thoughts as they arise. Focus on the silence between the thoughts, watch that expand with practice.
To begin with do not worry about mudras or yoga like postures. That is too much to think about. Simply sit comfortably with both feet on the ground and your back straight. As your practice develops and you mature into various techniques then you can adopt a mudras or a mantra or yogic posture. However, initially you simply want to teach yourself to sit comfortably and listen for the silence...the deep inner silence.
A consistent meditative practice can be the basis for all sorts of life improvement. You will discover your ground of being. You will begin to live this life from your inner beingness, not so much persuaded by outside influences. In time, with a consistent practice you will you will live this life as a lily of the field. You will savor the present moment, you'll be less concerned with past regrets and anxieties about the future.
For 2014...give yourself the gift of sight. You can start practicing now, or as soon as possible. When January 1st rolls around you will have some momentum already. Not an outer 'go get 'em' momentum. But an energy fueled by your (our) inner presence. Christmas/Solstice season is a beautiful time for renewed relationships. Renew your relationship to yourself. It is the best gift ever given.
