Many people feel that Spiritual discipline or Sadhana is not meant for people who have a lot more to see in life. Most people associate Sadhana with religion or faith. But there are valid and more important arguments that need to be considered for every individual, so as to follow a spiritual discipline pattern at the earliest. Interestingly, spirituality, common sense and pure intelligence are different names for the same facet.
It is important to understand the various limbs of Yoga. Unless one understands these limbs of spiritual practice, one shall not be sure or ascertained about the proper spiritual discipline that one should take up. Understanding the nature of mind and its relation to the spirit as well as the world is important. Understanding Jnana and Bhakti in that context becomes vital.
