My Dear Jaya Gopala,
Please accept my blessings. I am in due receipt of your letter dated August 18th, 1970, and I thank you very much for the nice sentiments expressed therein.
Regarding your marriage, I have no objection, but if you accept a girl for marriage she should be younger than you. At least she should not exceed your age. I know you are a very sincere devotee and I wish everyone of my devotees may purify himself from all material contamination and thus be eligible for entering into the association of the Supreme Personality of Godhead. Material life means indulging in sense gratification which diverts our attention from spiritual importance and thus we remain captive under the bewilderment of Maya. This is the most dangerous of our condition of life. Intelligent persons therefore try to avoid it under the protection of Krsna and the Spiritual Master.
Hope this will meet you in good health.
Your ever well-wisher,
A.C. Bhaktivedanta Swami
