Develop virtues like generosity, forgiveness and love. Mere Yogic Kriyas alone will not help you much. Do self-analysis daily and eradicate your faults and evil, slavish habits. Rectify your defects such as selfishness, pride, jealousy and hatred. You must cultivate a compassionate and loving heart first. At all times you must share what you have with others and practice selfless service. Then only will you get purity of heart.
Yoga is unity, identity, homogeneity, oneness and sameness with God.
Many aspirants neglect these preliminaries and jump, out of curiosity, to Yogic Kriyas for getting psychic powers. It is really a serious blunder. They will have a hopeless downfall. Therefore, be careful. Mere Yogic Kriyas cannot bring about the desired results. The purification of the heart is of paramount importance. The aspirant must free himself from lust, anger, greed, jealousy, hatred, egoism, vanity, attachment, pride and delusion. This is more difficult than control of breath or the practice of Yoga Asanas.
Virtuous qualities such as mercy, tolerance, adaptability, courage, patience, balance state of mind and cosmic love should be assiduously cultivated. Sages have always laid great stress on selfless service, generous charity, purity and simple living.
With firm faith, application, perseverance, careful attention to even small details, and fortitude in trials, you must set foot and proceed on the path of Sadhana.
Swami Sivananda Saraswati
The spiritual life is lived by the seeker in a body. Therefore, laws governing welfare of the physical body – suitable food, healthy habits, right posture, the correct amount of sleep, the tendency of the body to develop good and bad habits – have to be known.
