A balancing act

Hatha yoga cannot succeed without Raja yoga, nor Raja without hatha.
Therefore, practice the two to perfection (Hatha Yoga Pradipika, 2-76)

Finding and maintaining the balance between physical and meditative practices can be challenging at time for anyone on a journey of self development.
I realised early on in my yoga journey that Hatha yoga wouldn't be enough.
Sure, Hatha yoga practices make the body strong and flexible. And yes, freeing the body and breath from limiting patterns increases energy and will power, opening new possibilities. Through hatha yoga practice we become emotionally freer, stronger and more resilient. As our body and mind change, our life takes on a new direction. But without the container of ethical practices, these gifts remain mostly aimless.
Swami Purohit, in his commentary on the Yoga sutra (ISDN 0571103200), wrote: "I met many who practiced Hatha yoga as a stepping stone to Raja yoga, but the few who were mere Hatha yogis had great powers, strong healthy bodies and immense vanity. (...) They were generally amenable to praise, and some more worldly than average worldly men. This was the chief reason why I lost faith in Hatha yoga."
Time and time again over the past 25 years, I have met great hatha yoga practitioners who, without these preliminary ethical practices fell victim to pride, greed or lust. Their mind often lacked stability that meditative practices bring, and their lives reflected this.
Buddhist teachers fared better in that department. Their rigorous training in ethical and meditative practices apparently produced a far more stable mind. Although some of them sometimes fall victim to greed and delusion as well, their training in mindfulness, or simply peer pressure, meant this was less obvious and less frequent.
But, I also frequently met on meditation retreats long term Buddhist practitioners who didn't seem to make much progress. Their sitting posture was poor, and they didn't seem to have much awareness of it. They had been struggling with the same hindrances for years, and while they had often developed a high degree of tolerance for discomfort and could sit them out, progress was slow at best. They clearly would have benefited from some hatha yoga practices.
In my own practice, I have found that keeping a balance between the ethical and meditative practices of Raja yoga and the physical practices of Hatha yoga is indeed the best way to ensure steady progress.
