Sadhana is spiritual movement consciously systematized. Sadhana is the purpose for which we have come to this place.
Abhyasa and Sadhana are synonymous terms. The object of Sadhana is to release life from the limitations with which it is bound.
Sadhana is a lifelong process.
Every day, every hour, every minute, is an onward march.
Obstacles are innumerable in this great voyage.
But, so long as you hold God as thy guide, there is nothing to worry about.
You are sure to reach the other shore.
Some people have curiosity for the spiritual line.
They have no real thirsting for liberation.
They think that they will get certain powers or Siddhis (psychic powers) if they do some Yogic practices.
When they do not attain the powers, they lose patience and give up the practices, abandon the spiritual path, and pooh-pooh the Yogis and Yoga.
