If we can understand the true meaning and purport of meditation, the process to indulge in meditation one can easily burn ones karma, not only bad but also good karma.
Spirituality is never about burning bad karma, it is about negating karma to zero, burning both bad and good karma in totality. Only then one can become a pure soul atman, pure consciousness.
In my 55 years of spiritual travail I have yet to find a person who could detail to me the exact methodology of indulging in yoga meditation (yoga is termed meditation in English).
Yoga meditation is the path to reaching God in one’s lifetime. The urge of soul atman to merge with God is called yoga meditation. We can achieve this indulging in contemplation (chintan) to assimilate the hidden underlying precepts of spirituality contained in Bhagavad Gita.
Karma can be burnt in totality by establishing total control over five senses and mind. This becomes possible when we demolished our ego in totality. Demolition of ego is the worst part of spiritual travel, something very difficult to achieve. Only a hardened spiritual traveler like Swami Vivekananda finally succeeds.
We practically need becoming a Swami Vivekananda in real life to burn karma in totality.
To overpower five senses and mind, demolish ego control over desires and wishes has to be established in stages. We have to slowly realize that we are primarily a spirit, consciousness manifesting human form. To cleanse self of dross impurities within we have to indulge in nishkama karma yoga, never attaching self to fruits of karma performed.
Living life like a trustee is the essence of spirituality. We have to become a Karma Yogi like King Janaka or JRD Tata, two karma yogis par excellence. King Janaka (father of Sita in Ramayana) successfully indulged in affairs of his kingdom with an unattached attitude. He lived like a true Karma Yogi, never attaching self to day-to-day routines of his kingdom.
JRD Tata, scion of Tata Empire all his life worked like a caretaker, a trustee for whom nothing ever belonged to his personal self. JRD Tata believed in the fact that he was only a custodian of Tata Empire, nothing more. Even though JRD Tata understood nothing about Bhagavad Gita, he unknowingly all the time practiced principles of spirituality contained in Bhagavad Gita.
Working like a nishkama karma Yogi we can burn our karma in totality at the earliest. A true nishkama karma Yogi is never attached to even good karma. One practiced equanimity all the time maintaining a delicate balance between both shades of life good and bad karma. A good karma Yogi always was a 100% practitioner of positivity.
Mindless indulgence in karma produces bondage. It is this bondage that needs to be burnt in totality. Indulgence in nishkama karma yoga does not produce any karmic bondage ever. Living life like a nishkama karma Yogi one can easily burn ones karma in totality.
