To find Brahman one needs indulging in spirituality as detailed in Bhagavad Gita. There was never a shortcut path to knowing Brahman, reaching Brahman.
Unless one believed in teachings of Bhagavad Gita, the sermon of Lord Krishna to Arjuna in the battle of Mahabharata, one could never indulge in spirituality successfully to realize Brahman, God.
The entity of Brahman, God Almighty, creator of entire cosmos is invincible, could not be realized even by most advanced scientific methods, even religious practices (indulging in rituals).
Brahman the collective power of all souls’ atmans in cosmos in their pure form is realized undertaking the inner journey towards the spirit existing in heart. And for achieving this we have to demolish our ego in totality. Only then we can hear sweet small dictates of Lord Krishna coming from within our heart. The soul atman, spirit existing in our heart allegorically is Lord Krishna.
To reach Lord Krishna, to become a Lord Krishna, a pure soul atman one has to negate karma to zero. Demolishing ego and reducing our desires and wishes in stages one finally establishes total control over five senses and mind.
Furthermore practicing absolute celibacy for a period of 12 years in continuation we can awaken kundalini energy to its full potential. This results in full activation of brainpower 100%. Normal human beings used their brain 1 to 2% whereas enlightened souls used their brain 100%.
The moment human beings reached full potential of their brain 100%, one can distinctly realize see and meet Brahman in totality. This is the stage reached by Mahavira, Gautama Buddha even Jesus Christ and Prophet Mohammed.
Both Sri Ramakrishna Paramhansa and Maharshi Ramana after reaching state of enlightenment could also interact with Brahman on one-to-one basis every single day of their life. To find Brahman we have to become a Swami Vivekananda in real life. Anything less would not do.
