This is confirmed in Bhagavad-gītā by the Lord Himself: “One can understand Me only through devotional service.” In beginning His teaching of the Gītā, the Lord said to Arjuna, “Because you are My devotee, I shall teach these secrets to you.” Vedic knowledge means ultimately to understand the Supreme Lord, and the process of entering into His kingdom is devotional service. That is accepted by all authentic scriptures.
Relating to ones spouse as a servant of Krishna, understanding that their purpose in life is to please Krishna, rather than someone separate from God whose purpose is to satisfy our own needs is a practical implementation of this essential spiritual understanding. My wife/husband is an eternal servant of Krishna trying to reawaken their lost relationship with Him. This philosophical understanding can be practically applied in a marriage. We can ask ourselves, how can I support and encourage the devotional mood and service of my partner? What can I do to support their sadhana and service? To discuss each other's spiritual needs and aspirations and support one another in fulfilling them is important.
Aside from direct devotional activities in and around the home, it is also important that couples provide one another support. Taking time to listen to each another, to share experiences, and to spend time together are all important components of cultivating a meaningful friendship. Couples that sacrifice spending time together for other priorities, whether they be devotional or otherwise, are likely to become distant from one another over time which can result in all kinds of issues. Relationships take time and effort to maintain, cultivating a meaningful Krishna conscious relationship with your spouse is service. Investing time into your relationship is directly creating and maintaining stability within the Krishna consciousness society. Taking it to an extreme, men or women that are not satisfied within their marriage are likely to try and meet their needs outside of their marriage, causing so much disturbance and unhappiness within society. The maintenance, expansion, and progress of the Krishna consciousness movement are largely dependent on householders – who make up the largest social sector of our movement. For a householder sacrificing the quality of one’s relationship with one’s partner in the name of devotional service is folly.
NOTE: To cultivate a meaningful relationship among partner is the important aspect of Grhasta Ashram. Taking time to listen to each another, share experience, and spend time together are all important component of the relationship. Most Importantly one should understand our wife/husband is the servant of Krishna, their purpose in life is to please Krishna, not to satisfy our own need. All this activity that seemingly material actually part of the service to the Supreme Lord. Therefore one should take with full heart responsibility their cultivation of relationship in Grhasta ashram.
