Both sufferings and happiness relate to manifest physical world and had no locus standi in spiritual world dominated by spirit, souls’ atmans.
Journey of spirituality means removing dross impurities within soul atman. This removal of dross impurities within means undergoing different stages of sufferings and also happiness.
For human beings to evolve, for life to rotate in cosmic life cycle both happiness and sufferings were part of life, two sides of the same coin. Human beings can do nothing in absence of one. In absence of sufferings happiness carried no meaning. The value of happiness is measured in terms of sufferings one undergoes in day-to-day routines of life or the spiritual journey.
Spiritual journey towards self realization also demands indulging in karma with an unattached attitude. This in practical terms mean, cutting the bond of relationship with nears and dears. Lessening our desires and wishes in stages, one proceeds ahead on path of pure spirituality.
Lessening of desires and wishes, dismantling our relationship with parents, brothers and sisters even close relatives and friends, is painful, extremely excruciating! In my search for truth I do not know how many times I had to eat hell for breakfast, how many contemplations of suicide.
State of self realization is not that easily achieved, reached. One needs practicing patience, persistence and perseverance of the highest order like Swami Vivekananda. On the surface everything seems fine but it is only spiritual travelers who know the pitfalls of spirituality.
Mahavira, Gautama Buddha even Jesus Christ and Prophet Mohammed suffered immensely in their spiritual pursuit of cosmic truths of life. Cases are ripe about sufferings indulged by Sri Ramakrishna Paramhansa. When nearing state of self realization, people knowing nothing about spirituality threw stones at him. He was harassed at each and every stage of spiritual pursuit.
When we break our bond with the society, the journey onward becomes very painful. There is no one to assist us in the spiritual journey of life. Moreover people become our enemies, masses in general.
When lived Jesus Christ, he was brutally crucified. But now people world over praised him like a true son of god. The worth of a self realized soul is recognized by the society only after one has permanently departed from mother earth.
When Galileo stated earth moved around the sun, he was persecuted. But eventually he was proved right only after death.
Unmindful of sufferings a seeker must indulge in spirituality. If we feel we are not the right candidate for indulging in spirituality then we must not. It is better to quit early than never. I know many who quit spiritual journey midway after 15 years of indulgence, only to become patients of serious depression. If spirituality, self realization is not our cup of tea then we must enjoy worldly life and postpone everything spiritual to next manifestation by our soul atman.
